and <desc> for a11y. Let me write out all pixel cell rects. s_col=26.67 (80/3), s_row=25. Inset: 1.2px each side → rect x = colx+1.2, w=24.27; y = rowy+1.2, h=22.6. Round: w=24.3 h=22.6. Columns x-starts: c1=176, c2=202.67, c3=229.33. Rect x: 177.2, 203.9, 230.5. Rows y-starts: r1=156, r2=181, r3=206, r4=231, r5=256, r6=281, r7=306, r8=331. Rect y: +1.2: 157.2, 182.2, 207.2, 232.2, 257.2, 282.2, 307.2, 332.2. Cells: col1 r1–r8: 8 rects at x=177.2 col2 r2–r7: 6 rects at x=203.9 col3 r3–r6: 4 rects at x=230.5 Colors: base #FF3D8C, light #FF85C2. Checker: light when (colIndex+rowIndex) even, col index 1..3, row index 1..8. col1: light rows 1,3,5,7 → y rows r1(157.2), r3(207.2), r5(257.2), r7(307.2) col2: light rows 2,4,6 → 182.2, 232.2, 282.2 col3: light rows 3,5 → 207.2, 257.2 Hmm, will checker look noisy? Dithering vibe is intentional. Alternatively make all base with light only on top-left few cells (light source). I'll go checker — it reads as intentional dither pattern. Also maybe add a couple of "flying pixels" near the divider on left side — pixels breaking apart toward the right (upscale metaphor: pixels resolving). Cute: 3 small squares floating right of pixels at (250? no—) Let me add 2–3 small squares between pixel edge and divider... space is only ~27px wide with divider. Instead, floating pixels above/below near triangle: e.g., small squares at (238,150) size 10, (262,368) size 8, opacity .6 — sparks of upscaling. Subtle garnish. Maybe 3: (238,148) 10px light pink; (300,352) 9px gold .7; (196,368)? Let me place: spark A (246,146,10,#FF85C2,.8), spark B (306,346,9,#FFC93D,.8), spark C (188,342,7,#FF85C2,.5). They float around triangle silhouette. Nice detail. Wait, spark at (306,346): triangle bottom edge at x=306: y_bot=356-(306-176)*0.5556=283.8... hold on: y_bot(x)=356-(x-176)*0.5556 → at 306: 356-72.2=283.8. So (306,346) is well below/outside triangle (outside the shape, inside bg) — that's fine for a floating spark. Hmm but near bottom-right; visually balanced with kana above? OK. Actually reposition sparks to hug the triangle: one above apex (356,256): (352,196)? that's above top edge? top edge at x=352: y=156+(352-176)*0.5556=253.8; (352,196) is above the edge ✓ outside triangle, floating above apex region. spark: (350,206,10,gold). Another below-left: (200,344,9,pink .7): bottom edge at x=200: 356-13.3=342.7 → (200,344) just below edge ✓. Another right-mid outside apex right: (372,262,8,pink .5)? near kana? x=372 fine. Let me choose sparks: S1: x=346,y=200,10,#FFD34D,op .9 (above apex) S2: x=198,y=346,9,#FF85C2,op .8 (below left edge) S3: x=298,y=368,8,#FFC93D,op .6 — hmm near bottom, might collide wordmark (wordmark at y≈437+). y=368+8=376 < 437 fine. But divider line ends y=392 at x=256; S3 at x=298 no conflict. Maybe S3 unnecessary; 2–3 fine. I'll keep 3. Also add tiny "+" between? No. Right half gloss: path along top edge: M258 201 L342 248.6 stroke #FFD98A width 3 opacity .55 linecap round. Slight inset from edge. Also inner shadow/divider shading on right half near divider to suggest depth? skip. Handle ring gradient? plain white stroke ok, maybe stroke url(#edgeGrad)? Keep white. Bottom wordmark with slight tracking: letter-spacing 5. Also maybe split color: "MIKAI" white, "JA NAI" gold? Two tspans: MIKAI (white .9) + " JA NAI" (#FFC93D .95)? Cute emphasis on the pun. Do: <text> with tspans. Font: font-family="'Segoe UI', 'Inter', 'Helvetica Neue', Arial, sans-serif" font-weight="700" font-size="25" letter-spacing="6". Width estimate: "MIKAI JA NAI" = 12 chars incl 2 spaces. At 25px bold, avg advance ~15px + 6 tracking ≈ 21 → ~250px total. Centered at 256 → spans 131..381. Inside squircle ✓. Kana font stack: "'Noto Sans JP','Hiragino Sans','Yu Gothic','Meiryo','Noto Sans CJK JP',sans-serif". 未 watermark: might not render if no CJK font — but virtually all systems (Win/macOS/Linux with noto) have CJK. It's decorative (opacity .05); if missing, shows tofu box — risk! A tofu box at 340px would be ugly. Mitigate: draw 未 as simple strokes manually? 未 = horizontal short stroke, horizontal long stroke, vertical center stroke, left-falling stroke (ノ), right-falling stroke. I could draw it with lines: - vertical: M256 120 V400 (wait 未 structure: two horizontals, one vertical through, then 撇 and 捺 from center crossing). Let me approximate with strokes: - h1: M196 176 H316 (short top horizontal) - h2: M176 236 H336 (long second horizontal) - v: M256 148 V392 (vertical through both horizontals down to bottom) - 撇: M256 268 Q210 320 176 372 (left-falling curve) - 捺: M256 268 Q306 316 344 368 with a flick... plus thicker end. Use stroke width ~26, round caps, opacity .05. That renders everywhere identically. But is a giant faint 未 worth the code? It adds depth + meaning ("未見"/mikai). I'll hand-draw it with 5 strokes at low opacity. Actually opacity .06 white on dark bg — barely visible but adds texture. Let me set .07. Hmm, also consider: maybe make watermark not 未 but the "slash/negation" motif? The big kana? Keep 未, hand-drawn. Wait — hand-drawn 未 check: character 未: strokes: (1) short horizontal, (2) long horizontal, (3) vertical through center from above first horizontal to bottom, (4) left-falling from intersection area to lower-left, (5) right-falling to lower-right. My drawing approximates fine. Also add the vertical kana strip — same font-dependency concern; kana missing → tofu. Kana glyphs exist in most system fonts (Japanese fonts on Win/mac; Linux with noto). Meiryo on Windows, Hiragino on macOS, Noto on Linux — decent coverage. Acceptable; and it's decorative at 35% opacity, small. Alternatively hand-draw kana... too complex. Keep text with fallbacks. Or replace kana strip with "JA NAI" vertical latin small text? Latin always renders. Vertical "JA NAI" stacked letters J,A,N,A,I — could look cool like side label. Hmm. Kana is more anime-authentic; tofu risk small. I'll keep じゃない but include wide fallback chain. Fine. Divider line: from y=120 to y=392 — beyond triangle (154..358) by ~34px each side, classic compare look. Endpoints with round caps. Also: add faint "scanline" over pixel half? no, checker enough. Let me now also think: overall balance — triangle slightly left-of-center visually? Left edge 176, apex 356: mass center x ≈ (176+176+356)/3 = 236; visual center of play triangles usually good. Divider at 256 splits at 44% of width (80/180) — fine, matches split point where half-height ~55.6. Now assemble the SVG code. Defs: 1. bgGrad: linearGradient x1=0 y1=0 x2=1 y2=1: #2E2068 → #191243 → #0C0A1F. Actually 3 stops: 0% #31236E, 55% #1B1348, 100% #0D0A24. 2. centerGlow: radialGradient cx=.5 cy=.42 r=.6: #7A4DFF .28 → transparent. Hmm colors: use stop-opacity. 3. glowPink radial: cx=.5 cy=.5: stop0 #FF3D8C op .55, stop 60% op .18, 100% 0. 4. glowGold radial: #FFC93D .5 → 0. 5. triGrad (right half): linearGradient gradientUnits userSpaceOnUse x1=256 y1=230 x2=352 y2=270: stops #FF3D8C → #FF7A3D? Wait want divider-side color to match pixel magenta for continuity: start #FF4E9A, end #FFC93D via mid #FF8A4C: 3 stops: 0% #FF4E9A, 45% #FF7A4D, 100% #FFC93D. Nice sunset ramp. 6. gridPattern: 26×26 path stroke #A78BFA? white? use #FFFFFF op .05... pattern content: <path d="M26 0H0V26" fill="none" stroke="#FFFFFF" stroke-opacity="0.06" stroke-width="1"/>. Hmm maybe use purple tint #B9A8FF op .07. 7. edgeGrad: linear vertical: white .35 → white .02. 8. squircleClip. Body order: 1. squircle fill bgGrad 2. g clip=squircleClip: centerGlow rect, glowPink ellipse, glowGold ellipse, grid rect, 未 strokes 3. sparks (3 rects, slight rotation? axis-aligned) 4. pixel cells group 5. right half path + gloss stroke 6. divider line 7. handle circle + chevrons 8. kana text group 9. wordmark 10. edge stroke rect Glow implementation: <ellipse cx=210 cy=250 rx=150 ry=140 fill=url(#glowPink)/> etc. With userSpaceOnUse? radialGradient default objectBoundingBox works per-shape — fine. Wait glowGold should center near apex (330,255) rx 140. Let me double check right-half path with apex rounding: Top edge from (256,199.6) toward apex (356,256): direction (100,56.4), unit ≈ (0.871,0.491). Stop 12px before apex: (356-12*0.871, 256-12*0.491) = (345.5, 250.1). Bottom: (345.5, 261.9). Path: M256 199.6 L345.5 250.1 Q356 256 345.5 261.9 L256 312.4 Z. Also round the divider-side corners slightly? They're cut by the divider line; sharp ok, maybe tiny rounding: use straight corners; the divider line (5px) covers the seam anyway. Gloss: M262 203.6 L340 247.5 stroke #FFE1A0 sw 2.5 op .5. Divider: line x1=256 y1=122 x2=256 y2=390 stroke #FFF sw=5 op .92 linecap round. Hmm add slight shadow under handle? skip. Handle: circle r=17.5 fill #141031 stroke #FFF sw=4.5. Chevrons: <path d="M250.5 249.5 243.5 256 250.5 262.5 M261.5 249.5 268.5 256 261.5 262.5" fill=none stroke=#FFF sw=3 linecap round linejoin round>. Check inside r=17.5: chevron extent x 243.5..268.5 → within ±12.5 of center ✓, y 249.5..262.5 ±6.5 ✓. Kana: x=428: chars at y: じ 176, ゃ 218, な 262, い 306? spacing ~44, font-size 36. Baselines: 176,220,264,308. op .4 fill #E9E4FF. Slight: also add rotate? no. Check kana vs right triangle apex x=356 — kana x=428 clear. vs divider line top y=122 at x=256 — clear. Wordmark: y=452: <text x=256 y=452 text-anchor=middle font-size=24 font-weight=700 letter-spacing=6 fill...><tspan fill="#FFFFFF" fill-opacity=".92">MIKAI</tspan><tspan fill="#FFC93D"> JA NAI</tspan></text>. Note letter-spacing applies to tspans too; trailing spacing after last char negligible for centering (anchor middle accounts). Space before JA gives separation. Hmm one concern: letter-spacing in some renderers (older) inconsistent but fine. 未 strokes (draw within g opacity): stroke #CBB8FF opacity .07 sw=24 linecap round: - M256 150 V390 (vertical) — wait vertical should start above first horizontal. 未: vertical from top ~y=150 to bottom 390. - M198 180 H314 (short horizontal, y=180) - M170 240 H342 (long horizontal, y=240) - 撇: M256 262 C220 300 196 330 168 368 - 捺: M256 262 C292 298 320 330 350 366 Wait but this overlaps the play triangle region entirely (it's behind, opacity .07, fine — subtle texture). But it may also clash with glows — fine. Center the 未 around (256, ~268)? The play triangle center y=256. 未 spans y 150..390 centered ~270 ✓. Width 170..350 ✓. It'll read through the translucent areas... the triangle is opaque, covering center — 未 visible around edges. OK, decorative. Hmm, actually since triangle covers center, the 未 mostly shows above/below triangle — the bottom 撇捺 legs visible below triangle bottom (356) region y 356..390 — visible ✓, top vertical above 154 visible ✓. Subtle but nice. Grid pattern rect covers whole squircle — with 未 over it. Order: grid, then glows? Glows over grid (soft light) then 未? Let me order: bg → centerGlow → grid → glowPink/gold → 未 → sparks... Actually glows should sit above grid to soften it near triangle. Sequence inside clip: centerGlow, grid, glowPink ellipse, glowGold ellipse, 未. One more polish: add a very subtle top inner highlight arc on squircle: the edge stroke rect with edgeGrad handles it. Also drop shadow of triangle onto bg? A dark offset copy? Could add slight: right-half path duplicated offset (0,6) black .25 blurless? Without blur it's a hard shadow — meh. Skip; glows suffice. Let me also add rounded corners to pixel cells? No. Now write final code with nice formatting and comments. Also mention: works at 16px? At tiny sizes details vanish but silhouette holds. Provide brief customization notes (colors, rx). Keep explanation concise per style: a few bullets + code block. Maybe also give a "how to use" line: save as icon.svg. Let me carefully write coordinates as computed: Pixel cells (rects), x per column: c1 x=177.2, c2 x=203.9, c3 x=230.5; w=24.3, h=22.6, rx=2 (slight rounding actually might look nicer against flat bg... pixel art purist: rx=0. I'll use rx=1.5 for anti-alias softness. Eh, keep 0 for crisp pixels? Choose rx=2 — modern chunky pixel look. Hmm "pixel" reads better sharp. Final: rx=1.) Cells list with fills (L=light #FF85C2, D=base #FF3D8C): col1 (x=177.2): r1 y=157.2 L r2 y=182.2 D r3 y=207.2 L r4 y=232.2 D r5 y=257.2 L r6 y=282.2 D r7 y=307.2 L r8 y=332.2 D col2 (x=203.9): r2 182.2 L r3 207.2 D r4 232.2 L r5 257.2 D r6 282.2 L r7 307.2 D col3 (x=230.5): r3 207.2 L? checker: light when 3+r even → r odd → r3,r5 light: r3 207.2 L r4 232.2 D r5 257.2 L r6 282.2 D Hmm col1 r1 light at very top and col3 r3 light... checker consistent: pattern (col+row) even → light: c1r1(2)✓L, c1r2(3)D ✓ matches. c2r2(4) L ✓. c3r3(6) L ✓. Good. To reduce code repetition, define two rects via <use>? Cells have different positions; could use classes with CSS in <style>. SVG with <style> is fine for standalone icon file. I'll use a <style> block: .pd{fill:#FF3D8C}.pl{fill:#FF85C2}. Then rects: <rect class="pd" x=... y=.../>. Compact enough. Alternatively group per column with path... rects are clear. 18 rects fine. Let me also double-check pixel region left edge x=176 vs divider at 253..259: col3 ends 230.5+24.3=254.8 — overlaps divider start 253.5! Divider drawn after cells → covers overlap ✓. But cells poking past 253.5 under a 5px divider: divider covers 253.5..258.5; cell ends 254.8 → hidden ✓. Right half starts at 256 under divider ✓. Visually: pixel edge and divider merge — good (compare seam). Gap between col2 end (203.9+24.3=228.2) and col3 start 230.5 = 2.3 ✓; col1 end 201.5 vs col2 start 203.9 = 2.4 ✓; rows gap: 22.6 h + 2.4 ✓ consistent. Top pixel cell r1 y 157.2..179.8; smooth triangle top at x~189: y_top=157.3 — cell pokes slightly above smooth edge line? The pixel half doesn't need to match smooth edge exactly; silhouette of pixel steps vs smooth half edge — they only meet at divider. Left of divider, pixel steps form their own stepped diagonal; slight mismatch with the implied full-triangle edge is invisible since no smooth edge exists on left. ✓. Now, will the stepped pixel shape read as "half a play button"? 8/6/4 staircase descending left→right toward divider, with apex continuing via smooth half to point. Yes ✓. Right half fill gradient direction: from (256,235) to (356,268): x1=256 y1=235 x2=356 y2=268, stops: #FF4E9A, #FF7A4D at 50%, #FFC93D. The divider-side color #FF4E9A ≈ pixel base #FF3D8C — close enough for continuity across the seam (slightly different = "different filter" vibe, fine). Actually, maybe stronger story: pixel side slightly desaturated/dull (old quality), right side vivid. Make pixel base #E23A85 / light #F07FB8 (a bit duller), right side ramp starting vivid #FF4E9A → #FFC93D. Yes! Dull left, vivid right = "upscaled/HDR". Do that: .pd fill #DE3D86, .pl fill #EE83B9. And glows: pink glow behind left (dimmer .4), gold behind right (.55). Sparks colors update: S1 gold #FFC93D, S2 #EE83B9, S3 #FFC93D smaller. Edge stroke: rect x=36 y=36 w=440 h=440 rx=108 stroke url(#edgeGrad) sw=2.5 fill none. Slightly inset from squircle (32..480) to sit inside edge. Hmm inner border typically exactly on edge with 1px inset: use x=33.5 w=445? Keep 36/440 fine. Let me reconsider rx: 448 size squircle rx=112 = 25% — iOS-like ✓. Title/desc: <title>Mikai Ja Nai

The user wants a cool SVG app icon as code for "Mikai Ja Nai" — an unofficial mikai.me desktop client. It's a Qt 6 + libmpv player with Anime4K and AnimeJaNai upscaling, HDR, and a Compare workstation. Let me think about the design. The name "Mikai Ja Nai" is a play on "mikai.me" and "AnimeJaNai". The word "ja nai" (じゃない) means "isn't it / not" in Japanese — a pun: "Mikai Ja Nai" = "Not Mikai" (unofficial client). So the icon could play with negation — like an eye with a slash, or a play button with a "not" slash, or the kanji flavor. Key concepts to represent: - Video player (play triangle, mpv) - Anime upscaling (Anime4K / AnimeJaNai) — pixel → sharp, upscale arrows, before/after split (Compare workstation) - HDR — vivid colors, gradient - Desktop client — rounded squircle app icon - Japanese anime aesthetic — kawaii, katakana maybe, "未" (mikai means "not yet seen" — 未見 mikai = unseen!). Actually 未見 (mikai) means "not yet seen" in Japanese. And "じゃない" (ja nai) = "is not". So "Mikai Ja Nai" ≈ "Not unseen" — cute pun. The mikai.me site is anime streaming. Design idea: A rounded squircle (app icon) with a dark background (player aesthetic), a play button that's split into two halves — one half pixelated (original) and one half smooth/sharp (upscaled) — representing the Compare workstation and upscaling. Add a diagonal slash or "jā nai" strike? Or a crossline like the "not" symbol crossed out (crossed-out = "nai" negation)? Maybe: A play triangle where the left half is low-res pixel blocks and the right half is a clean gradient (upscaled). A dividing line (the compare slider). Add small "4K" or "JaNai" badge? Keep text minimal for icon legibility. Alternative: An eye with play button pupil, since mikai = "not yet seen", and "Ja Nai" = "it's not". Could do a play button shaped like a cat-eye (anime style). Hmm. I think the pixel-to-sharp split play button is the strongest concept: it instantly communicates "video player + upscaling + compare". Add a subtle slash through it referencing "Ja Nai" (negation) — a diagonal "not" slash in a contrasting color could look cool, like a stylized ◢ with a slash. Let me build it as a proper SVG code deliverable: - 512×512 viewBox - Squircle background with gradient (HDR-ish vivid: deep purple → indigo → magenta? or dark with neon accents) - Play triangle: left half composed of chunky pixel squares (low-res), right half smooth with gradient + maybe glow (upscaled) - Compare divider line with a small handle (like compare sliders) — vertical line through the triangle - A diagonal slash (negation "nai") in accent color, subtle - Maybe a small "未" or "じゃない" text? Could add tiny katakana "ジャナイ" at bottom for flavor, but small text in icons may look cluttered. Maybe a subtle "MiKAI JA NAI" wordmark? Icons usually don't have full names. Could include a tiny "4K" badge or "HDR" tag. Also can offer multiple variants? The user said "create cool app svg icon as code" — deliver one polished SVG, maybe with brief explanation. I could provide one main icon and optionally a monochrome/alternate. Keep response focused: one main SVG code block, plus short notes on design rationale and how to adapt sizes. Maybe include two variants: full color and a compact variant. I'll do one main detailed icon, and mention it scales. Let me design coordinates carefully. Canvas: 512×512. Squircle: rect x=32 y=32 width=448 height=448 rx=112 (iOS-like superellipse approximation). Use a gradient background: dark navy/charcoal (#0E0F1A → #1A1030) with a subtle radial glow. Actually for "HDR" vibe, use vivid gradient: e.g., from #7C3AED (violet) to #EC4899 (pink) to #22D3EE (cyan)? Anime icons often use vivid gradients. Let me do: background dark (#0D0B1E to #1C1440 diagonal) with a soft radial cyan/pink glow — the neon comes from the triangle halves. That keeps the icon readable. Play triangle: centered-ish, pointing right. Triangle points: apex at (352, 256), top-left (176, 150), bottom-left (176, 362). Let me compute: For a nice triangle centered at (256, 256): left edge x=176, apex x=356, top y=156, bottom y=356, apex y=256. Left half (pixelated): clip the triangle to x ≤ 256, render as chunky pixels. I can create the pixel effect by drawing the left half of triangle with a clipPath, then overlaying a grid of squares clipped to it, or simpler: draw a series of stacked rectangles approximating a stepped triangle. Stepped triangle pixels: columns of increasing height. Let me construct with squares of size 28px in a stepped arrangement: Pixel triangle steps (classic pixel play icon): columns from left: heights increasing. Using unit = 36px squares, centered at y=256: - Column 1 (x=176–212): 1 square tall? That's a small pixel triangle: columns 1,3,5,7... Actually typical pixel play: leftmost column 1 unit, next 3, next 5, next 7... but a play triangle is full height on left. Hmm — pixelated left half of a play triangle: the left edge is the tall edge. Stepped pixels decreasing toward apex: column heights 7,5,3,1 for a right-pointing triangle made of squares (like a staircase). That's the classic "pixel play button". So left half: 4 columns of squares, sizes: column widths equal (e.g., 30px), heights: 7 units, 5, 3, 1? That gives a triangle silhouette from tall-left to point-right. But our left half spans x=176→256 (80px). With 3 columns of ~26px: heights 5,3,1 units of 26px: heights 130, 78, 26. Total silhouette matches half triangle? Half-triangle at x=256 has half of full height ≈ (356-156)/2 * ... let's check: full triangle height at x: linear from 200 at x=176 to 0 at x=356. At x=256: 200*(356-256)/180 ≈ 111. So left-half outline at x=256 is ±55.5 from center. Stepped pixels: choose square size s=30. Columns at x=176 (w=27?), hmm, easier: build a stepped shape with 4 steps covering x=176..272, heights stepped: at x fraction f from left edge (0) to apex (1), half-height = 100*(1-f). Steps: Let me just design a self-contained pixel triangle on the left half with 3 columns: - s = 26 - Column A: x=176..202, height 5s=130, centered: y=191..321 - Column B: x=202..228, height 3s=78, y=217..295 - Column C: x=228..254, height 1s=26, y=243..269 This makes a decreasing staircase: widths equal but heights 5,3,1 — silhouette half-heights: 65, 39, 13 at column centers x≈189, 215, 241. The true half-triangle at x=189: 100*(356-189)/180 ≈ 92.8; at 215: 78.3; at 241: 63.9. Our steps are shorter than the true triangle. Alternative: make pixel triangle its own stylization — doesn't need to match the smooth half exactly; the visual contrast is what matters. But for the "compare" concept, the two halves should mirror each other: left half = pixelated version of the right half. So the pixel silhouette should follow the half-triangle shape stepped. Better approach: define the smooth right half-triangle via clip, and define left half as stacked rows of pixel squares clipped to left half of the same triangle. Rows of squares: horizontal rows (height s) with varying left... no — pixelation via rows: each row is a rectangle from x=176 to a stepped right edge. Actually a common pixelation: mosaic grid — divide triangle area into grid cells, fill cells whose center is inside the triangle. Left half only. That naturally follows the triangle silhouette stepped. Let me compute with grid s=26, origin at triangle bounds. Triangle bounds: x 176..356 (w=180), y 156..356 (h=200). Left half: x 176..256 (w=80). Grid aligned to bounds: cell size 26.7 ≈ w/6.75... let me choose s = 25: x cells: 176,201,226,251,276,301,326,351. y cells: 156,181,206,231,256,281,306,331 (last partial 331..356). For left half (x<256), columns 176–201, 201–226, 226–251, 251–276 (partially). Rows: for each column, fill rows where cell center is inside triangle. Triangle edges: top edge from (176,156) to (356,256): y_top(x) = 156 + (x-176)*100/180 = 156 + (x-176)*0.5556. Bottom edge: y_bot(x) = 356 - (x-176)*0.5556. Column 1 (x 176..201, center 188.5): y_top=156+12.5*0.5556≈162.9; y_bot≈349. Rows with centers inside: row1 center 168.5 ✓(168.5>162.9), rows 1..7 centers 168.5,193.5,218.5,243.5,268.5,293.5,318.5 all < 343.5? y_bot for bottom-edge check: cell must be fully-ish inside; simpler: fill cells fully inside: column 1: y from 162.9 to 349 → cells fully inside: 181..331 (rows 2..7, y 181–356? row 7 is 331..356, partially). Let me instead fill by center rule for a chunkier look: center inside → fill. Column 1 centers x=188.5: inside y range 162.9..349.0: centers 168.5,193.5,218.5,243.5,268.5,293.5,318.5,343.5 → 8 cells (rows 1..8). Row 8 is y 331..356. Column 2 centers x=213.5: y_top≈156+20.8≈176.9; y_bot≈335.1: centers inside: 181.5,206.5,231.5,256.5,281.5,306.5,331.5 → 7 cells (rows 2..8). Column 3 centers x=238.5: y_top≈190.8; y_bot≈321.2: centers inside: 206.5,231.5,256.5,281.5,306.5 → 5 cells (rows 3..7). Column 4 (x 251..276) is split by the compare line at 256. I could end pixels at x=251 (3 columns of 25 = 75 wide, ending at 251) and leave 251..256 gap? Or make column 4 narrower (251..256, 5px — too thin). Better: make the pixel grid span exactly 176..256 with 3 columns of 26.67 or 4 columns of 20. 4 columns of 20 might look too fine; 3 chunky columns of ~26.7: Columns: 176..202.67, 202.67..229.33, 229.33..256. Rows of s=25. Recompute with these: Col1 center 189.3: y_top≈163.4, y_bot≈348.6. Rows (s=25 from 156): centers 168.5,193.5,218.5,243.5,268.5,293.5,318.5,343.5 → 8 cells (rows 1..8, y 156..356). Col2 center 216: y_top≈182.2, y_bot≈329.8: centers inside: 193.5,218.5,243.5,268.5,293.5,318.5 → 6 cells (rows 2..7). Col3 center 242.7: y_top≈201.0, y_bot≈311.0: centers inside: 206.5,231.5,256.5,281.5,306.5 → 5 cells (rows 3..7). So pixel cells: Col1: y 156,181,206,231,256,281,306,331 (8 cells, each h=25, last 331..356 ✓) Col2: y 181..331 (6 cells) Col3: y 206..306 (5 cells) That's a nice stepped mosaic 8/6/5. Chunky and readable. To add pixel charm, I can vary shades slightly (like a mosaic of 2–3 tones of magenta/pink) so it reads as "low-res" but still attractive. Or single flat color with gaps (grid lines) — gaps make pixelation obvious. I'll use slight gaps (cells drawn at full cell minus 1.5px inset... simpler: exact cells but background shows through via stroke gaps? Easiest: draw cells with size s-2 with 1px offset). I'll compute cells with 1.5px padding: rect x+1 y+1 w=s-2 h=s-2. But stepped edges: fine. Actually cleaner: draw each cell with rx=3 for slight rounding? Pixel art usually sharp; keep sharp with small gaps. Right half (smooth, "upscaled"): right half-triangle from x=256 to apex (356,256), with top edge to (176,156) etc. Right half polygon: (256, 176.2)?? Let's compute: at x=256, y_top = 156+80*0.5556 = 200.4; y_bot = 311.6. So right half: points (256,200.4) → (356,256) → (256,311.6). Fill with a vivid gradient (cyan→violet or pink→orange). Add a subtle inner glow/highlight edge. Maybe rounded joins via stroke-linejoin with a stroke same color to round corners — or just sharp; sharp apex looks fine, but a rounded apex is nicer. I can use a path with slight rounding: use stroke with round join: stroke width 8, stroke same as fill gradient, paint-order... simpler: draw path with rounded corners manually: apex rounded r≈10. Compare divider: vertical line at x=256 from y≈120 to y≈392 (taller than the triangle), with a small circular handle at center (256,256)? But the handle would sit on the play triangle — that's okay; compare sliders have handles. Style: 4px line, white 90%, handle circle r=14 with gradient ring and small left-right arrows ‹ › inside (classic compare icon). Arrows: two tiny triangles pointing left and right. That reinforces "Compare workstation". Negation slash ("Ja Nai"): a diagonal slash could conflict with the divider. Alternative negation symbol: circle with diagonal slash (🚫-like) as small badge at top-right? Like a small "not" badge: circle outline with slash, containing "JA NAI"? Could be cute: top-right small circle-slash badge reading as "not official". Hmm, might clutter. Alternative: put text "JA NAI" as small label under the icon on a pill, or vertical Japanese text "じゃない" on the side in small size. Icons at small sizes lose text; but desktop app icons can include wordmarks. I'll add a small wordmark "MIKAI JA NAI" at bottom in clean sans, letter-spaced, low opacity — optional and tasteful. And maybe a tiny "未見" (mikai) vertical on left? Might be too much. Keep: bottom wordmark "MIKAI JA NAI" small caps, plus maybe "4K • HDR" mini tags? Let's not overstuff. I'll include the wordmark and a small "HDR" chip? Actually a subtle approach: right half gradient labeled... no. Let me finalize composition: 1. Background squircle: gradient dark indigo (#141031 → #241a4d → #0e0c22 radial + linear), subtle noise? Skip noise; add faint grid (pixel grid) pattern at low opacity across background — ties into pixel theme. A faint dotted grid of 26px cells at 4–6% opacity. Nice. 2. Radial glow behind triangle: ellipse with cyan/pink blur (feGaussianBlur or radial gradient with alpha). Use radialGradient circle behind, colors: left glow pink (#FF4FA0) low alpha, right glow cyan (#3AE1FF). 3. Left half pixel triangle: 19 cells (8+6+5), fill: flat hot pink gradient? To show "low-res", use a stepped gradient — each cell a slightly different shade from a magenta ramp (darker at top-left to brighter at bottom). Or all same magenta (#FF3D8A) with some cells lighter (#FF6FB0) randomly for mosaic feel. I'll do base #FF3D8A with accent cells #FF71B8 in a pattern (e.g., checker-ish random). Let me assign: cells where (col+row) even → lighter. Col1 rows1..8: rows 1,3,5,7 lighter; Col2 rows2..7: rows2,4,6 lighter... wait col index + row index even. Col1 (idx1): rows with 1+r even → r odd → 1,3,5,7. Col2: 2+r even → r even → 2,4,6. Col3: 3+r even → r odd → 3,5,7? Col3 rows are 3..7 → r=3,5,7 lighter. That's a checker mosaic — looks like dithering, very "anime upscale" appropriate (dithering!). 4. Right half smooth triangle: gradient from #FF3D8A? No — to contrast "before (pixel, dull)" vs "after (upscaled, vivid)": right side vivid cyan→electric violet gradient (#3AE1FF → #8A5CFF) or gold? Anime4K branding often cyan/teal. AnimeJaNai logo colors? AnimeJaNai uses orange/yellow? I recall AnimeJaNai logo has yellow/orange. Not sure; I'll go with a vivid cyan→violet with slight pink rim. Add a 2px inner stroke highlight (#FFFFFF33) along top edge for gloss. Also add subtle "upscale arrows" on right half? Three small chevrons pointing right/up? Might clutter. Skip. 5. Compare divider: line x=256 from y=118 to y=394, white 85%, rounded caps, width 5. Handle: circle r=17 at (256,256), fill #0E0C22 (bg) with 4px white ring? Or gradient ring. Inside handle: ‹ › arrows in white. This is the classic compare handle — very recognizable. But the handle at center overlaps the divider line through the play button — fine, that's how compare UIs look (line runs through image with handle at center). 6. Small negation detail: on the handle? Could make the handle a "slash" — the compare handle with a diagonal slash inside instead of arrows = "Ja Nai" (not). Ooh — combine: handle circle with diagonal slash = 🚫 = "nai". But compare handles use arrows... A slash inside the handle reads as "no". Hmm, mixing metaphors. Alternatively place a small slashed-circle badge at top-right of the squircle (like app badge), colored yellow (#FFC93D) — reads as "unofficial/not". I'll add it: circle r=34 at (408,104)? Squircle corner radius 112 means top-right area around (396,108) is inside. Badge: outer circle stroke 10, diagonal line at 45°, maybe tiny "非" character? A slash circle alone might read as "prohibited". With the app name it reads as the pun. I think a small slash badge is a nice wink. Make it subtle: white 70% stroke. Actually — better idea for the "Ja Nai" pun that's cleaner: the play button itself gets a slash? No, slash through play = "no video" — bad semantics. Badge approach is safer. Alternatively, use text: put "じゃない" vertically along the right edge, tiny, white 40%. Vertical Japanese text in SVG: place each kana as separate text chars stacked. That's flavorful: じゃない stacked at x=452? Squircle inner edge ~x=448... The kana "じゃない" is 4 chars (small ゃ). Stack at x=430, y from 150, step 44, font-size 30. Might collide with badge. Choose one: badge OR kana. I'll do kana vertical strip on right side — more "anime" and directly encodes "ja nai". Hmm, but at icon small sizes it vanishes; that's fine, it's a flourish. Decision: include both? Risk clutter. I'll include the vertical kana strip on the right edge (subtle) and skip the slash badge... but the slash badge is a stronger "unofficial" signal. Let me evaluate space: Play triangle occupies center. Right side from x=360 to 440 free vertically. Kana strip there works. Badge at top-right corner also works. Could do kana strip on right edge from y≈140 to 300, and leave badge out. Alternatively "未" kanji watermark behind triangle, large, 20% opacity — "未見" (mikai = unseen). A big 未 behind the play triangle at low opacity adds depth and the name pun. Nice! Place 未 centered, font-size 320, opacity 0.08, white. Not every environment has CJK fonts though — SVG text depends on system fonts. For an app icon, text rendering variability is risky (fonts differ across Linux/Windows). Mitigate: use generic font-family with fallbacks, accept variation; or convert to paths (too complex by hand). I'll use text with font-family="sans-serif" fallbacks and keep text decorative (low opacity / small), so variance is acceptable. For the wordmark "MIKAI JA NAI" bottom, sans-serif is safe cross-platform. Let me reconsider whether to keep it simpler: Core icon = pixel/smooth split play button + compare divider handle + background. Flourishes: kana strip, wordmark, faint grid, big 未 watermark. That's a rich but coherent composition. Also HDR hint: add tiny "HDR" tag? Could place small pill "4K · HDR" under triangle? Might clutter with wordmark. Skip HDR text; the vivid gradient implies it. Or put tiny "ANIME4K" on left and "JANAI" on right? Cute: labels like compare "BEFORE/AFTER"! Compare UIs label sides. Add micro-labels: left of pixel half "4K" ... hmm "Anime4K" vs "AnimeJaNai" are the two upscale filters. A tiny label under each half: left "ANIME4K", right "JA NAI"? That directly nods to both technologies and the before/after compare. But small text under triangle may collide with divider handle. Place labels at y≈400 outside triangle: left label centered at x≈200 "ANIME4K", right at x≈312 "JANAI". Then wordmark at bottom y≈452 "MIKAI JA NAI". Getting texty. Maybe drop the per-side labels and keep just the bottom wordmark + kana. Cleaner. Final composition plan (512×512): - defs: gradients (bg linear, glowRadial pink, glowRadial cyan, tri gradient right, grid pattern), clipPath for squircle (for grid pattern + watermark clipping), clipPath for right half triangle? Right half drawn as explicit polygon path, no clip needed. Pixel cells explicit rects, no clip needed. - Squircle: rect 32,32,448,448 rx=112 fill url(#bg). - Faint grid: pattern of 26px squares stroked white 3% — fill a rect 32..480 clipped by squircle clip. Pattern: . Apply rect fill url(#grid) with clip. - Big 未 watermark: text x=256 y=330 font-size=340 text-anchor=middle fill=#fff opacity .06, clip to squircle. font-family "'Noto Sans JP','Hiragino Sans','Yu Gothic',sans-serif". Hmm 未 at 340px centered — extends y≈ 330-250..330+60 ≈ 80..390 fine. - Glows: two blurred circles: pink at (205,256) r=120 opacity .35; cyan at (315,245) r=120 opacity .35 — using radial gradients with alpha (no filter needed if gradient alpha to 0). Use radialGradient stops color→transparent. Cheaper than filters and renders everywhere. - Pixel cells (19 rects) fill colors: base #FF4D9D; light #FF85C0. Add per-cell slight rounding rx=2? Sharp is more pixel — rx=0. Inset 1.5px each side: rect x=cellX+1.5 y+1.5 w=22 h=22? cell s=25 → w=22. Wait, I set columns as 176..202.67 (s=26.67) horizontally and rows s=25. Slight non-square cells; acceptable but let me make uniform: use s=25 for both. Columns: 176..256 = 80px → 3.2 columns. Non-integer. Options: s=20 → 4 columns of 20 (finer pixels: 4 cols, rows: recompute) or shift grid: make left half from x=171? Or widen triangle left edge to x=166 so left half is 90px (s=30 → 3 columns exactly). Let's adjust triangle: left edge x=166, apex x=366? Keep apex 356; then triangle w=190, center offset. Hmm, symmetrical placement: triangle centroid should sit at 256: for play triangle, visual center ~ 45% from left edge. Let me set left edge x=171, apex x=361 → w=190, midpoint of mass ≈ 171+0.42*190 ≈ 251 — close to 256. Left half at divider x=256: left width 85 → 3 columns of 28.33. Not clean. Cleaner: choose divider x=256, left half width 81 with s=27 → 3 columns exactly (81px). Rows s=27: triangle y 154..358 (h=204): 204/27 = 7.56 rows... rows from y=154: 154,181,208,235,262,289,316,343 (partial 343..358 = 15px). Let me recompute silhouette with left x=171, apex x=361, top y=154, bottom y=358, center y=256. Half-height H=102. Slope: 102/95 ≈ 1.0737 per px. Right half at x=256: offset=85 from left → y_top=154+85*1.0737≈245.3?? wait that's wrong: full triangle: at left edge x=171 height is full (154..358, half-height 102), at apex 361 height 0. y_top(x)=154+(x-171)*0.5368... no: y_top goes from 154 at x=171 to 256 at x=361: slope = 102/190 = 0.5368. At x=256: 154+85*0.5368 ≈ 199.6. y_bot ≈ 312.4. Good, matches earlier ≈. Left half grid s=27, columns at x=171,198,225,252 (col width 27; col3 = 225..252, leaving 252..256 4px gap — bad). Make 3 columns of 28.33? Ugly numbers in code but fine — or accept 3 columns of 27 ending at 252 with 4px gap before divider... the divider line is 5px wide at x=256 (253.5..258.5) — the gap 252..253.5 is 1.5px, fine actually! Divider covers 253.5..258.5. Left pixels end at 252, right triangle starts at 258.5? Right half polygon starts at x=256 under the divider anyway. Visual gap between pixels and divider ≈ 1.5px — okay. Hmm wait, actually simpler alternative: forget exact geometric mapping — design the pixel triangle as its own independent stepped shape (staircase), and the smooth triangle as its own half. The "compare" reads fine even if pixel steps are approximate. I'll craft nice round numbers: Let me define: - Triangle full: left edge x=176, apex x=356, top y=156, bottom y=356, center y=256. (w=180, H=100, slope=0.5556) - Divider at x=256, width 6 (253..259), from y=118 to y=394, rounded caps. - Left pixel half: 3 columns s=26: x=174..200, 200..226, 226..252 (start 174? make 176..252 = 76 → 3 cols of 25.33). Gah. OK final approach: I'll allow non-integer-ish numbers; SVG handles decimals fine. Use s=25.33? Let me just use: left half from x=176 to 256, 3 columns of 80/3 = 26.6667. Rows: y from 156 to 356, 8 rows of 25. Cells (col centers): c1=189.3, c2=216.0, c3=242.7. y_top(c1)=156+(189.3-176)*0.5556=163.4; rows filled where cell fully inside? Let me use "cell inside if its vertical span within [y_top, y_bot]" for cleanliness: y ranges per row (s=25): r1:156–181, r2:181–206, r3:206–231, r4:231–256, r5:256–281, r6:281–306, r7:306–331, r8:331–356. Col1 (x 176..202.67): y_top=163.4 (within r1), y_bot=348.6 (within r8). Fully-inside cells: r2..r7 fully; r1 partial (top cut 163.4>156), r8 partial. If I use center-in rule: r1 center 168.5>163.4 ✓, r8 center 343.5<348.6 ✓ → 8 cells. Center-in gives chunkier, more "mosaic" look. Use center-in: Col1: r1..r8 (8 cells) Col2 (center 216.0): y_top=182.2, y_bot=329.8 → centers: r2 193.5 ✓ ... r7 318.5 ✓; r1 168.5 ✗, r8 343.5 ✗ → 6 cells (r2..r7) Col3 (center 242.7): y_top=197.1? compute: (242.7-176)=66.7*0.5556=37.06 → y_top=193.1; y_bot=318.9 → centers in: r3 218.5 ✓, r4 243.5 ✓, r5 268.5 ✓, r6 293.5 ✓; r2 193.5 < 193.1? 193.5>193.1 ✓ barely (0.4px). Risky visually (barely inside → cell pokes above smooth edge slightly). Adjust: use r3..r6 (4 cells) plus maybe r7? r7 center 318.5 vs y_bot 318.9 ✓ barely too. Symmetric issue. I'll manually choose: col3 rows r3..r6 (4 cells) — silhouette 8/6/4, hmm asymmetric vs earlier 8/6/5. 8/6/4 gives a cleaner diagonal step actually (steps of -2). Wait 8→6→4: consistent -2. So pixel cells: col1 r1–r8, col2 r2–r7, col3 r3–r6. Total 18 cells. Nice. Cell rects (x, y, w=26.67 h=25, inset 1.5 → w=23.7 h=22): col1 x=177.5? Let me place cells with 0.75 inset: x=cell.x+0.75, w=25.17? To keep code simple, I'll draw cells at full size but with a 1px gap by using shape... simplest: define cells as x=cx-13.33+1.5 etc. I'll just enumerate rect x/y with insets baked: col1 x: 176+1.2=177.2, w=26.67-2.4=24.3. Eh — decimals fine. Actually you know, let me simplify the whole thing: use integer-friendly geometry by changing divider to x=255 and pixel region x=176..254? I'm overengineering. Decimal coords are completely fine in SVG. I'll keep decimals but round to 1 decimal. Let me now define pixel cell colors with dithering (checker): lighter for (col+row) even: col1 (c=1): rows1–8: light when 1+r even → r odd → r1,3,5,7 light. col2: light when r even → r2,4,6. col3: light when 3+r even → r odd → r3, r5. Light: #FF7FBF, base: #FF3D8C. Maybe also a deepest tone for a couple cells for texture: skip, two tones fine. Actually add slight variation: col1 r4&r5 (middle) could be brighter? Keep checker. - Right smooth half: polygon (256,199.6) (356,256) (256,312.4) with rounded apex: path: M256 199.6 L344 250.2 Q356 256 344 261.8 L256 312.4 Z. Let me verify apex rounding: apex at (356,256). Approach lines: top edge slope 0.5556 down-right; at x=344: y=256-(356-344)*0.5556=249.3; bottom edge at x=344: y=262.7. Use Q control (356,256): M256 199.6 L344 249.3 Q356 256 344 262.7 L256 312.4 Z. Fill: linearGradient from (256,190) to (356,262)? Direction: make it vivid: from #FFB03A (gold, AnimeJaNai-ish?) to #FF3D8C? Hmm. Concept: left = "original" (magenta pink), right = "upscaled" — should feel premium/HDR: cyan→violet is classic "4K HDR" tech vibe. But then icon palette = pink + cyan + violet on indigo — cohesive neon. Alternatively right = gold/amber → hot pink continuing left's hue family but brighter/sharper. I like pink→gold: left pixel magenta, right gradient from #FF3D8C at divider to #FFC93D at apex? Gradient direction along x. That makes a unified triangle that transitions from retro-pixel-magenta to vivid gold — "before/after" with energy. Then accents (divider, handle, kana) white. Background indigo/violet. Palette: deep indigo bg, magenta pixels, magenta→gold triangle, white details. That's warm and distinctive (not the generic cyan-purple). Add right-half top-edge gloss: a thin lighter stroke along top edge: path M256 199.6 L344 249.3 stroke #FFE9A8 opacity .6 width 3? Or an inner highlight line. Keep subtle. - Divider & handle: line x=256 y1=120 y2=392 stroke #FFFFFF stroke-width=5 opacity .9, stroke-linecap round. Handle: circle cx=256 cy=256 r=18 fill=#171233 (dark) stroke #FFFFFF stroke-width=4. Inside: two arrows: left arrow polygon points (247,256) triangle pointing left: "251,249 251,263 244,256"? Wait arrows ‹ ›: left chevron at x≈248, right at x≈264. Use small paths: M250 249 L243 256 L250 263 (stroke) and M262 249 L269 256 L262 263 (stroke), stroke white width 3, round caps, fill none. Chevrons read as "compare/drag". But wait: handle circle r=18 centered on divider — it sits on top of the triangle halves boundary. Good. - Kana vertical "じゃない" right side: text elements stacked: x=430, chars: じ (y=170), ゃ (y=212), な (y=254), い (y=296), font-size 34, fill white opacity .35, text-anchor middle, font-family "'Noto Sans JP','Hiragino Sans','Yu Gothic','Meiryo',sans-serif". Check squircle boundary: squircle x 32..480 with rx 112: at x=430, y range: corner circle center (368,144) r112: at x=430 dx=62, dy=√(112²-62²)=√(12544-3844)=√8700≈93.3 → top boundary y=144-93.3=50.7 at x=430... that's the corner region: for x>368 top boundary = 144-√(112²-(x-368)²)... at x=430: y_top≈50.7. So kana from y=170 well inside. Right boundary at y=256: x max = 480. Kana at x=430 fine, may slightly overlap divider handle? Handle at 256 — no. Overlap with triangle apex (356)? kana x=430 clear. Hmm wait — kana vertical: じゃない with small ゃ — stacking each char vertically: じ, ゃ, な, い. The small ゃ stacked looks odd in vertical writing (normally じ+ゃ combine vertically as じゃ with small ya below ji — that's actually correct for tategaki: each char in its own cell, small ゃ in its cell). Fine. Alternatively put "Ja Nai" slash badge instead... I'll go with kana. Actually, let me reconsider clutter: with 未 watermark + grid + kana + wordmark, is it too busy? The kana strip at 35% white on dark bg at x=430 — subtle. OK. - Wordmark bottom: "MIKAI JA NAI" centered x=256 y=456, font-size 26, letter-spacing 6, fill white opacity .85, font-weight 600, font-family "'Inter','Segoe UI',system-ui,sans-serif". Check bottom boundary: squircle bottom edge y=480 minus stroke; y=456 baseline inside (boundary at x=256 is y=480). Good. Maybe add tiny dot separators: "MIKAI JA NAI" fine as-is. Also small sub "unofficial client · 4K HDR"? Might overload; skip or add second tiny line? I'll skip — keep one line. Hmm, but is wordmark at y=456 too close to bottom edge (24px above 480)? Slightly tight but okay for baseline (descenders none in caps). Baseline 456, cap height ~19 → text occupies 437–456, edge at 480: 24px margin below. Fine. - Also maybe a tiny "4K" chip on the pixel side and "HDR" on smooth side at y≈400? I said skip. Let me do side micro-labels instead of... no. Keep as planned. Actually — one more idea: tiny label "ANIME4K" bottom-left under pixel half and "JANAI" bottom-right under smooth half, mimicking compare before/after labels, font-size 13, opacity .5, at y=402: left x=205, right x=307. This is a meaningful nod (the two upscale engines + compare workstation). I think it adds real information and charm. But clutter risk near handle line (line ends y=392; labels at 402 below line ends — line ends at 392, labels at 402 baseline → gap 10px, fine, but line cap round at 392 close to labels vertically... labels x=205 and 307, line at x=256 — horizontally separated, fine). Hmm, decide: include side labels? They make the story explicit: pixel side = "ANIME4K"?? Wait semantics: Anime4K and AnimeJaNai are both upscalers, not before/after. The compare workstation compares... versions. Labeling pixel side "ANIME4K" and smooth "JANAI" is a bit semantically off but reads as a playful credit to both engines. Alternatively label sides "BEFORE"/"AFTER". I think BEFORE/AFTER is semantically clean for compare, and the engine names go... nowhere. Or skip labels entirely. Let me skip side labels — cleaner. The icon already tells: player + upscale + compare. The name is in the wordmark. - Add a subtle bottom reflection/ellipse shadow under triangle? A soft dark ellipse below for depth: ellipse cy=400? With glow already, maybe a soft dark vignette at edges: radial gradient overlay dark at corners? The bg gradient can handle that: bg linear from #241B4D (top-left) to #120E2B (bottom-right) + radial highlight center? Let me define bg: linearGradient (135°): stops #2A1B5E → #171136 → #0D0A22. Plus radial glow center (256,250) #6D3AFF opacity .25 r=230 for center luminosity. Plus pink glow behind left triangle, gold glow behind right apex. Glows as radial gradients with alpha: - glowPink: cx=210 cy=250 r=130: #FF3D8C opacity .5 → 0. - glowGold: cx=330 cy=250 r=130: #FFC93D opacity .45 → 0. Squircle clip for grid & watermark & glows (so glows don't spill past rounded corners). Define clipPath squircleClip with same rect. Let me also round the pixel cells slightly? No — sharp. Edge highlight on squircle: inner stroke: rect 34.5,34.5,443,443 rx=110 fill none stroke url(#edgeGrad) stroke-width=3 opacity .5? A white→transparent top-light edge adds polish. Use linearGradient vertical white .35 → white 0. I'll add rect stroke with gradient (white .3 at top, .05 at bottom). Also add small "HDR" rainbow accent? The gold/pink covers it. Now, code layout. Use viewBox "0 0 512 512". Include width/height 512. Add and <desc> for a11y. Let me write out all pixel cell rects. s_col=26.67 (80/3), s_row=25. Inset: 1.2px each side → rect x = colx+1.2, w=24.27; y = rowy+1.2, h=22.6. Round: w=24.3 h=22.6. Columns x-starts: c1=176, c2=202.67, c3=229.33. Rect x: 177.2, 203.9, 230.5. Rows y-starts: r1=156, r2=181, r3=206, r4=231, r5=256, r6=281, r7=306, r8=331. Rect y: +1.2: 157.2, 182.2, 207.2, 232.2, 257.2, 282.2, 307.2, 332.2. Cells: col1 r1–r8: 8 rects at x=177.2 col2 r2–r7: 6 rects at x=203.9 col3 r3–r6: 4 rects at x=230.5 Colors: base #FF3D8C, light #FF85C2. Checker: light when (colIndex+rowIndex) even, col index 1..3, row index 1..8. col1: light rows 1,3,5,7 → y rows r1(157.2), r3(207.2), r5(257.2), r7(307.2) col2: light rows 2,4,6 → 182.2, 232.2, 282.2 col3: light rows 3,5 → 207.2, 257.2 Hmm, will checker look noisy? Dithering vibe is intentional. Alternatively make all base with light only on top-left few cells (light source). I'll go checker — it reads as intentional dither pattern. Also maybe add a couple of "flying pixels" near the divider on left side — pixels breaking apart toward the right (upscale metaphor: pixels resolving). Cute: 3 small squares floating right of pixels at (250? no—) Let me add 2–3 small squares between pixel edge and divider... space is only ~27px wide with divider. Instead, floating pixels above/below near triangle: e.g., small squares at (238,150) size 10, (262,368) size 8, opacity .6 — sparks of upscaling. Subtle garnish. Maybe 3: (238,148) 10px light pink; (300,352) 9px gold .7; (196,368)? Let me place: spark A (246,146,10,#FF85C2,.8), spark B (306,346,9,#FFC93D,.8), spark C (188,342,7,#FF85C2,.5). They float around triangle silhouette. Nice detail. Wait, spark at (306,346): triangle bottom edge at x=306: y_bot=356-(306-176)*0.5556=283.8... hold on: y_bot(x)=356-(x-176)*0.5556 → at 306: 356-72.2=283.8. So (306,346) is well below/outside triangle (outside the shape, inside bg) — that's fine for a floating spark. Hmm but near bottom-right; visually balanced with kana above? OK. Actually reposition sparks to hug the triangle: one above apex (356,256): (352,196)? that's above top edge? top edge at x=352: y=156+(352-176)*0.5556=253.8; (352,196) is above the edge ✓ outside triangle, floating above apex region. spark: (350,206,10,gold). Another below-left: (200,344,9,pink .7): bottom edge at x=200: 356-13.3=342.7 → (200,344) just below edge ✓. Another right-mid outside apex right: (372,262,8,pink .5)? near kana? x=372 fine. Let me choose sparks: S1: x=346,y=200,10,#FFD34D,op .9 (above apex) S2: x=198,y=346,9,#FF85C2,op .8 (below left edge) S3: x=298,y=368,8,#FFC93D,op .6 — hmm near bottom, might collide wordmark (wordmark at y≈437+). y=368+8=376 < 437 fine. But divider line ends y=392 at x=256; S3 at x=298 no conflict. Maybe S3 unnecessary; 2–3 fine. I'll keep 3. Also add tiny "+" between? No. Right half gloss: path along top edge: M258 201 L342 248.6 stroke #FFD98A width 3 opacity .55 linecap round. Slight inset from edge. Also inner shadow/divider shading on right half near divider to suggest depth? skip. Handle ring gradient? plain white stroke ok, maybe stroke url(#edgeGrad)? Keep white. Bottom wordmark with slight tracking: letter-spacing 5. Also maybe split color: "MIKAI" white, "JA NAI" gold? Two tspans: MIKAI (white .9) + " JA NAI" (#FFC93D .95)? Cute emphasis on the pun. Do: <text> with tspans. Font: font-family="'Segoe UI', 'Inter', 'Helvetica Neue', Arial, sans-serif" font-weight="700" font-size="25" letter-spacing="6". Width estimate: "MIKAI JA NAI" = 12 chars incl 2 spaces. At 25px bold, avg advance ~15px + 6 tracking ≈ 21 → ~250px total. Centered at 256 → spans 131..381. Inside squircle ✓. Kana font stack: "'Noto Sans JP','Hiragino Sans','Yu Gothic','Meiryo','Noto Sans CJK JP',sans-serif". 未 watermark: might not render if no CJK font — but virtually all systems (Win/macOS/Linux with noto) have CJK. It's decorative (opacity .05); if missing, shows tofu box — risk! A tofu box at 340px would be ugly. Mitigate: draw 未 as simple strokes manually? 未 = horizontal short stroke, horizontal long stroke, vertical center stroke, left-falling stroke (ノ), right-falling stroke. I could draw it with lines: - vertical: M256 120 V400 (wait 未 structure: two horizontals, one vertical through, then 撇 and 捺 from center crossing). Let me approximate with strokes: - h1: M196 176 H316 (short top horizontal) - h2: M176 236 H336 (long second horizontal) - v: M256 148 V392 (vertical through both horizontals down to bottom) - 撇: M256 268 Q210 320 176 372 (left-falling curve) - 捺: M256 268 Q306 316 344 368 with a flick... plus thicker end. Use stroke width ~26, round caps, opacity .05. That renders everywhere identically. But is a giant faint 未 worth the code? It adds depth + meaning ("未見"/mikai). I'll hand-draw it with 5 strokes at low opacity. Actually opacity .06 white on dark bg — barely visible but adds texture. Let me set .07. Hmm, also consider: maybe make watermark not 未 but the "slash/negation" motif? The big kana? Keep 未, hand-drawn. Wait — hand-drawn 未 check: character 未: strokes: (1) short horizontal, (2) long horizontal, (3) vertical through center from above first horizontal to bottom, (4) left-falling from intersection area to lower-left, (5) right-falling to lower-right. My drawing approximates fine. Also add the vertical kana strip — same font-dependency concern; kana missing → tofu. Kana glyphs exist in most system fonts (Japanese fonts on Win/mac; Linux with noto). Meiryo on Windows, Hiragino on macOS, Noto on Linux — decent coverage. Acceptable; and it's decorative at 35% opacity, small. Alternatively hand-draw kana... too complex. Keep text with fallbacks. Or replace kana strip with "JA NAI" vertical latin small text? Latin always renders. Vertical "JA NAI" stacked letters J,A,N,A,I — could look cool like side label. Hmm. Kana is more anime-authentic; tofu risk small. I'll keep じゃない but include wide fallback chain. Fine. Divider line: from y=120 to y=392 — beyond triangle (154..358) by ~34px each side, classic compare look. Endpoints with round caps. Also: add faint "scanline" over pixel half? no, checker enough. Let me now also think: overall balance — triangle slightly left-of-center visually? Left edge 176, apex 356: mass center x ≈ (176+176+356)/3 = 236; visual center of play triangles usually good. Divider at 256 splits at 44% of width (80/180) — fine, matches split point where half-height ~55.6. Now assemble the SVG code. Defs: 1. bgGrad: linearGradient x1=0 y1=0 x2=1 y2=1: #2E2068 → #191243 → #0C0A1F. Actually 3 stops: 0% #31236E, 55% #1B1348, 100% #0D0A24. 2. centerGlow: radialGradient cx=.5 cy=.42 r=.6: #7A4DFF .28 → transparent. Hmm colors: use stop-opacity. 3. glowPink radial: cx=.5 cy=.5: stop0 #FF3D8C op .55, stop 60% op .18, 100% 0. 4. glowGold radial: #FFC93D .5 → 0. 5. triGrad (right half): linearGradient gradientUnits userSpaceOnUse x1=256 y1=230 x2=352 y2=270: stops #FF3D8C → #FF7A3D? Wait want divider-side color to match pixel magenta for continuity: start #FF4E9A, end #FFC93D via mid #FF8A4C: 3 stops: 0% #FF4E9A, 45% #FF7A4D, 100% #FFC93D. Nice sunset ramp. 6. gridPattern: 26×26 path stroke #A78BFA? white? use #FFFFFF op .05... pattern content: <path d="M26 0H0V26" fill="none" stroke="#FFFFFF" stroke-opacity="0.06" stroke-width="1"/>. Hmm maybe use purple tint #B9A8FF op .07. 7. edgeGrad: linear vertical: white .35 → white .02. 8. squircleClip. Body order: 1. squircle fill bgGrad 2. g clip=squircleClip: centerGlow rect, glowPink ellipse, glowGold ellipse, grid rect, 未 strokes 3. sparks (3 rects, slight rotation? axis-aligned) 4. pixel cells group 5. right half path + gloss stroke 6. divider line 7. handle circle + chevrons 8. kana text group 9. wordmark 10. edge stroke rect Glow implementation: <ellipse cx=210 cy=250 rx=150 ry=140 fill=url(#glowPink)/> etc. With userSpaceOnUse? radialGradient default objectBoundingBox works per-shape — fine. Wait glowGold should center near apex (330,255) rx 140. Let me double check right-half path with apex rounding: Top edge from (256,199.6) toward apex (356,256): direction (100,56.4), unit ≈ (0.871,0.491). Stop 12px before apex: (356-12*0.871, 256-12*0.491) = (345.5, 250.1). Bottom: (345.5, 261.9). Path: M256 199.6 L345.5 250.1 Q356 256 345.5 261.9 L256 312.4 Z. Also round the divider-side corners slightly? They're cut by the divider line; sharp ok, maybe tiny rounding: use straight corners; the divider line (5px) covers the seam anyway. Gloss: M262 203.6 L340 247.5 stroke #FFE1A0 sw 2.5 op .5. Divider: line x1=256 y1=122 x2=256 y2=390 stroke #FFF sw=5 op .92 linecap round. Hmm add slight shadow under handle? skip. Handle: circle r=17.5 fill #141031 stroke #FFF sw=4.5. Chevrons: <path d="M250.5 249.5 243.5 256 250.5 262.5 M261.5 249.5 268.5 256 261.5 262.5" fill=none stroke=#FFF sw=3 linecap round linejoin round>. Check inside r=17.5: chevron extent x 243.5..268.5 → within ±12.5 of center ✓, y 249.5..262.5 ±6.5 ✓. Kana: x=428: chars at y: じ 176, ゃ 218, な 262, い 306? spacing ~44, font-size 36. Baselines: 176,220,264,308. op .4 fill #E9E4FF. Slight: also add rotate? no. Check kana vs right triangle apex x=356 — kana x=428 clear. vs divider line top y=122 at x=256 — clear. Wordmark: y=452: <text x=256 y=452 text-anchor=middle font-size=24 font-weight=700 letter-spacing=6 fill...><tspan fill="#FFFFFF" fill-opacity=".92">MIKAI</tspan><tspan fill="#FFC93D"> JA NAI</tspan></text>. Note letter-spacing applies to tspans too; trailing spacing after last char negligible for centering (anchor middle accounts). Space before JA gives separation. Hmm one concern: letter-spacing in some renderers (older) inconsistent but fine. 未 strokes (draw within g opacity): stroke #CBB8FF opacity .07 sw=24 linecap round: - M256 150 V390 (vertical) — wait vertical should start above first horizontal. 未: vertical from top ~y=150 to bottom 390. - M198 180 H314 (short horizontal, y=180) - M170 240 H342 (long horizontal, y=240) - 撇: M256 262 C220 300 196 330 168 368 - 捺: M256 262 C292 298 320 330 350 366 Wait but this overlaps the play triangle region entirely (it's behind, opacity .07, fine — subtle texture). But it may also clash with glows — fine. Center the 未 around (256, ~268)? The play triangle center y=256. 未 spans y 150..390 centered ~270 ✓. Width 170..350 ✓. It'll read through the translucent areas... the triangle is opaque, covering center — 未 visible around edges. OK, decorative. Hmm, actually since triangle covers center, the 未 mostly shows above/below triangle — the bottom 撇捺 legs visible below triangle bottom (356) region y 356..390 — visible ✓, top vertical above 154 visible ✓. Subtle but nice. Grid pattern rect covers whole squircle — with 未 over it. Order: grid, then glows? Glows over grid (soft light) then 未? Let me order: bg → centerGlow → grid → glowPink/gold → 未 → sparks... Actually glows should sit above grid to soften it near triangle. Sequence inside clip: centerGlow, grid, glowPink ellipse, glowGold ellipse, 未. One more polish: add a very subtle top inner highlight arc on squircle: the edge stroke rect with edgeGrad handles it. Also drop shadow of triangle onto bg? A dark offset copy? Could add slight: right-half path duplicated offset (0,6) black .25 blurless? Without blur it's a hard shadow — meh. Skip; glows suffice. Let me also add rounded corners to pixel cells? No. Now write final code with nice formatting and comments. Also mention: works at 16px? At tiny sizes details vanish but silhouette holds. Provide brief customization notes (colors, rx). Keep explanation concise per style: a few bullets + code block. Maybe also give a "how to use" line: save as icon.svg. Let me carefully write coordinates as computed: Pixel cells (rects), x per column: c1 x=177.2, c2 x=203.9, c3 x=230.5; w=24.3, h=22.6, rx=2 (slight rounding actually might look nicer against flat bg... pixel art purist: rx=0. I'll use rx=1.5 for anti-alias softness. Eh, keep 0 for crisp pixels? Choose rx=2 — modern chunky pixel look. Hmm "pixel" reads better sharp. Final: rx=1.) Cells list with fills (L=light #FF85C2, D=base #FF3D8C): col1 (x=177.2): r1 y=157.2 L r2 y=182.2 D r3 y=207.2 L r4 y=232.2 D r5 y=257.2 L r6 y=282.2 D r7 y=307.2 L r8 y=332.2 D col2 (x=203.9): r2 182.2 L r3 207.2 D r4 232.2 L r5 257.2 D r6 282.2 L r7 307.2 D col3 (x=230.5): r3 207.2 L? checker: light when 3+r even → r odd → r3,r5 light: r3 207.2 L r4 232.2 D r5 257.2 L r6 282.2 D Hmm col1 r1 light at very top and col3 r3 light... checker consistent: pattern (col+row) even → light: c1r1(2)✓L, c1r2(3)D ✓ matches. c2r2(4) L ✓. c3r3(6) L ✓. Good. To reduce code repetition, define two rects via <use>? Cells have different positions; could use classes with CSS in <style>. SVG with <style> is fine for standalone icon file. I'll use a <style> block: .pd{fill:#FF3D8C}.pl{fill:#FF85C2}. Then rects: <rect class="pd" x=... y=.../>. Compact enough. Alternatively group per column with path... rects are clear. 18 rects fine. Let me also double-check pixel region left edge x=176 vs divider at 253..259: col3 ends 230.5+24.3=254.8 — overlaps divider start 253.5! Divider drawn after cells → covers overlap ✓. But cells poking past 253.5 under a 5px divider: divider covers 253.5..258.5; cell ends 254.8 → hidden ✓. Right half starts at 256 under divider ✓. Visually: pixel edge and divider merge — good (compare seam). Gap between col2 end (203.9+24.3=228.2) and col3 start 230.5 = 2.3 ✓; col1 end 201.5 vs col2 start 203.9 = 2.4 ✓; rows gap: 22.6 h + 2.4 ✓ consistent. Top pixel cell r1 y 157.2..179.8; smooth triangle top at x~189: y_top=157.3 — cell pokes slightly above smooth edge line? The pixel half doesn't need to match smooth edge exactly; silhouette of pixel steps vs smooth half edge — they only meet at divider. Left of divider, pixel steps form their own stepped diagonal; slight mismatch with the implied full-triangle edge is invisible since no smooth edge exists on left. ✓. Now, will the stepped pixel shape read as "half a play button"? 8/6/4 staircase descending left→right toward divider, with apex continuing via smooth half to point. Yes ✓. Right half fill gradient direction: from (256,235) to (356,268): x1=256 y1=235 x2=356 y2=268, stops: #FF4E9A, #FF7A4D at 50%, #FFC93D. The divider-side color #FF4E9A ≈ pixel base #FF3D8C — close enough for continuity across the seam (slightly different = "different filter" vibe, fine). Actually, maybe stronger story: pixel side slightly desaturated/dull (old quality), right side vivid. Make pixel base #E23A85 / light #F07FB8 (a bit duller), right side ramp starting vivid #FF4E9A → #FFC93D. Yes! Dull left, vivid right = "upscaled/HDR". Do that: .pd fill #DE3D86, .pl fill #EE83B9. And glows: pink glow behind left (dimmer .4), gold behind right (.55). Sparks colors update: S1 gold #FFC93D, S2 #EE83B9, S3 #FFC93D smaller. Edge stroke: rect x=36 y=36 w=440 h=440 rx=108 stroke url(#edgeGrad) sw=2.5 fill none. Slightly inset from squircle (32..480) to sit inside edge. Hmm inner border typically exactly on edge with 1px inset: use x=33.5 w=445? Keep 36/440 fine. Let me reconsider rx: 448 size squircle rx=112 = 25% — iOS-like ✓. Title/desc: <title>Mikai Ja NaiSplit play-button icon: pixelated half meets upscaled half across a compare slider. Also add role="img" aria-label? title suffices. Final check on kana positions vs squircle right edge: at y=176..308, right boundary: for y in [144,368] right edge is... corner circles at top-right center (368,144) r112: for y between 144 and 256?? Actually right edge: x=480 for y in [144, 368]. Kana at x=428 with font-size 36 → glyph width ~36 → right extent ~446 < 480 ✓. Baseline positions: じ baseline 190? I said y=176 as baseline earlier vs 190 — set baselines: 188, 232, 276, 320 (spacing 44). Top glyph じ cap ~156 → fine (> 50 boundary). Bottom い baseline 320, below descender ~330 < 368 straight-edge region... at y=330, right boundary: bottom-right corner circle center (368,368): at y=330, dy=38 → dx=√(12544-1444)=√11100≈105.3 → boundary x=368+105.3=473.3 ✓ x=428 fine. Kana color #EFEAFF opacity .4. Wordmark baseline y=452. Bottom boundary: bottom edge straight y=480 for x in [144,368] — at x=131..381 corners? At x=131: bottom-left corner circle center (144,368) r112: point (131,452): dx=13,dy=84 → dist=85.1 <112 inside ✓. Fine. Also add letter-spacing only via attribute. One more consideration:
