It should be:\n- 3D with 360-degree movable camera\n- Animated (man on horse)\n- Educational content about management concepts\n- \"Vibe coded\" - meaning stylish, aesthetic, engaging\n\nI'll use Three.js to create this. Let me plan:\n\n1. **Scene setup**: A nice environment - maybe a stylized low-poly world with ground, sky, trees, sun\n2. **Horse**: Built from primitives (boxes, cylinders, spheres) - body, head, legs, tail, mane. Animated with leg movement, head bobbing, tail sway\n3. **Man/Rider**: Sitting on horse - body, head, arms that gesture (like explaining), maybe a pointing gesture animation\n4. **Management concepts**: Floating 3D text/panels showing concepts like:\n - Leadership\n - Planning\n - Organizing\n - Leading\n - Controlling (POLC framework)\n - Communication\n - Delegation\n - Teamwork\n - Time Management\n - Decision Making\n \n5. **Speech bubble / info panel**: Shows the current concept being explained\n6. **OrbitControls**: For 360-degree camera movement\n7. **Animation loop**: Horse idle animation, rider gesturing, floating concept icons rotating around\n\nLet me build this carefully:\n\n- Use Three.js from CDN (use a version that works with OrbitControls from CDN). I'll use the older style with script tags:\n - `https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js`\n - `https://cdn.jsdelivr.net/npm/three@0.128.0/examples/js/controls/OrbitControls.js`\n\n- Low-poly aesthetic with flat shading\n- Nice gradient sky\n- Fog for depth\n- Trees (cone + cylinder)\n- Clouds (groups of spheres)\n- Sun with glow\n\nHorse construction:\n- Body: stretched box or capsule\n- Neck: angled box\n- Head: box\n- Ears: small cones\n- Legs: cylinders with lower legs\n- Tail: curved\n- Mane: boxes along neck\n\nAnimation:\n- Legs trot in diagonal pairs (like walking gait)\n- Body bobbing\n- Head nodding\n- Tail swaying\n- Rider arm gestures - rotating arm up/down as if explaining\n- Occasionally the horse moves in a circle? Or stays in place? Maybe the horse walks slowly in a circle around a central area - that would be cool with 360 camera. Actually, let me make the horse walk in a circular path so there's movement.\n\nManagement concepts display:\n- Rotating ring of concept panels around the horse, OR\n- A \"podium\"/holographic board in front, OR\n- Floating text sprites that cycle\n\nI'll do: floating holographic panels arranged in a circle around the center, each with a concept name. The current concept gets highlighted and a big speech bubble (HTML overlay or 3D sprite) shows the explanation.\n\nActually a nice approach: HTML UI overlay with:\n- Title\n- Concept card that cycles every ~6 seconds with concept name + description\n- Controls hint\n- Buttons to navigate concepts\n\nPlus 3D floating text sprites around the scene.\n\nFor 3D text, I can use canvas textures on planes - easier than TextGeometry with font loading.\n\nLet me code:\n\n```html\n\n\n\n\nManagement Wisdom — The Horseback Mentor\n\n\n\n\n\n

...

\n\n\n\n```\n\nConcepts list (POLC + more):\n1. Planning — \"Set goals and chart the course. A rider plans the route before the journey.\"\n2. Organizing — \"Arrange resources and people. Like saddling the horse properly before riding.\"\n3. Leading — \"Inspire and guide others. The rider leads the horse with gentle direction, not force.\"\n4. Controlling — \"Monitor progress and correct course. Check the reins, adjust the path.\"\n5. Delegation — \"Trust your team with tasks. Even the best rider trusts the horse to run.\"\n6. Communication — \"Clear signals get clear results. A gentle tug speaks volumes.\"\n7. Decision Making — \"Choose wisely and quickly. Hesitation at a fork in the trail costs time.\"\n8. Time Management — \"Prioritize what matters. The journey is long — pace yourself.\"\n9. Teamwork — \"Together we go further. Horse and rider move as one.\"\n10. Motivation — \"Inspire with purpose. A carrot works better than a stick.\"\n\nEach concept displayed with an icon maybe.\n\n3D scene:\n- Ground: large circle, green, with some texture variation\n- Path: a circle path where the horse walks\n- Trees: scattered around\n- Rocks\n- Mountains in background (cones)\n- Clouds floating\n- Sun\n- Concept panels: 5-10 planes arranged in a circle, canvas textures with concept names, gently bobbing and always facing camera (sprites might be easier — use THREE.Sprite with canvas texture)\n\nI'll use sprites for concept labels so they always face camera.\n\nHorse walking in circle: position = center + radius*(cos(a), 0, sin(a)), rotation.y = -a (tangent direction). Walk gait: legs alternate.\n\nRider: sits on saddle, one hand holds reins, other arm gestures. When concept changes, trigger a \"pointing\" gesture - arm raises toward the highlighted concept sprite.\n\nHighlight: the active concept sprite scales up and glows, maybe moves closer.\n\nSpeech bubble: HTML div positioned at top, or a 3D bubble above rider's head? HTML is easier and more readable. I'll do a nice HTML card at bottom/top with concept name and description, animated transitions. Plus a 3D speech bubble above the man's head with \"💡\" or the concept name.\n\nLet me also add:\n- Auto-rotate camera option\n- Mouse drag to orbit, scroll to zoom\n- Buttons: Prev/Next concept, pause/play animation\n\nColor palette: warm sunset vibe? Or pleasant day? Let me do a golden-hour vibe: warm sky gradient (orange to purple), warm lighting. \"Vibe coded\" suggests aesthetic. Golden hour with low-poly stylized look would be beautiful.\n\nActually let me do a dreamy sky: gradient from deep blue-purple at top to warm orange at horizon. Fog matching. Directional light warm orange. Hemisphere light.\n\nRenderer: shadows enabled, PCFSoft.\n\nLet me write the horse with flat-shaded materials (MeshStandardMaterial flatShading: true).\n\nHorse geometry plan:\n- Group `horse`\n - body: BoxGeometry(2.2, 1, 0.9) rounded? Use cylinder rotated or a scaled sphere for body. Use CapsuleGeometry? r128 doesn't have CapsuleGeometry (added in r131+). So use a stretched sphere: SphereGeometry(0.7, 8, 6) scaled to (1.8, 1, 0.9). Flat shaded looks nice.\n - chest/rump spheres for shape\n - neck group at front top: box angled\n - head: box with snout\n - ears: cones\n - mane: small boxes along neck\n - legs: 4 groups at corners, each with upper cylinder and lower cylinder + hoof box\n - tail: cone or curved boxes\n\nLeg animation: rotate upper leg group around x-axis with sin offsets. Diagonal pairs: front-left + back-right in phase, front-right + back-left opposite. Lower leg adds secondary bend.\n\nRider:\n- legs straddling (angled cylinders)\n- torso box/sphere\n- arms: groups with upper+forearm\n- head sphere with hat (cowboy hat! cylinder brim + dome) - cowboy hat fits horse theme\n- The right arm gestures: rotates toward active concept\n\nSpeech bubble 3D: a plane sprite above rider head with canvas texture, updated with current concept keyword and an icon. Canvas texture updated when concept changes.\n\nAlso add floating particles (dust motes / fireflies) for vibe.\n\nAdd a circular fence? Maybe not necessary. Add a stone circle path where horse walks.\n\nGround details: grass tufts (small cones), flowers (small spheres on stems), scattered.\n\nBackground: ring of mountains (big cones, purple-blue), trees (cone layers), clouds (sphere clusters drifting).\n\nCamera: start at nice angle, OrbitControls target at horse center (0, 2, 0). Auto-rotate slowly, stop on user interaction (controls autoRotate true; any pointerdown disables? OrbitControls handles autoRotate continuing; I'll add toggle button).\n\nHUD design:\n- Top center: title \"🐎 The Horseback Mentor — Management Concepts\"\n- Bottom center: concept card: number, title, description, prev/next buttons, progress dots\n- Bottom right: controls hint \"Drag to orbit • Scroll to zoom\"\n- Buttons: ⏸ pause, 🔁 auto-rotate toggle\n\nFont: use a Google font? External fonts via link are allowed (full HTML). Use 'Poppins' or similar. Include link tag.\n\nNow the concept cycling: every 7 seconds advance. Pause button stops both horse? Pausing should pause concept cycling maybe; keep horse animation. I'll have pause for auto-advance of concepts. Actually \"Pause\" could pause the horse too. Let me do: Play/Pause toggles the whole animation (horse stops, fireflies stop). Separate \"Auto\" button for auto-rotate camera. Concept auto-advance continues unless animation paused? Hmm, keep simple: one Pause button pauses animations and auto-advance. Prev/Next buttons manual navigation resets timer.\n\nSound: skip audio (autoplay issues). \n\nLet me now write the code carefully.\n\nKey structures:\n\n```js\nconst CONCEPTS = [\n {icon:'🎯', name:'Planning', desc:'...', color:'#ffd166'},\n ...\n];\n```\n\nCanvas sprite maker:\n\n```js\nfunction makeTextSprite(text, opts){\n const canvas = document.createElement('canvas');\n canvas.width = 512; canvas.height = 256;\n const ctx = canvas.getContext('2d');\n // draw rounded rect bg\n ...\n const tex = new THREE.CanvasTexture(canvas);\n const mat = new THREE.SpriteMaterial({map: tex, transparent: true});\n const spr = new THREE.Sprite(mat);\n spr.scale.set(...);\n return spr;\n}\n```\n\nConcept ring: radius ~9, height ~4, 10 sprites around. Active one: scale lerp to bigger, color ring highlight — simpler: rebuild texture with highlight style when active. Rebuild is fine.\n\nHorse walk path radius ~5, speed angular ~0.25 rad/s → linear speed 1.25 units/s. Leg gait frequency matched: freq = speed / strideLength * 2π roughly; stride ~1 → freq ~ 1.25*π ≈ 4 rad/s? Legs swing sin(t*4). Looks fine.\n\nThe horse group: create `horseRig` group positioned each frame: pos on circle, facing tangent. Inside, body bob: y += sin(t*freq*? )*0.05, pitch slight.\n\nActually the horse should walk around center where... hmm, but then rider explaining to concept ring sprites surrounding — fine, the rider gestures toward the active sprite. The bubble above head shows concept.\n\nWait — maybe nicer: horse stays near center walking in a small circle, concept panels orbit around at radius 9. The active panel could rotate to be... no, keep panels fixed in ring; camera auto-rotates to see them all. Good.\n\nLet me handle the rider's gesture: right arm group; target rotation depends on active panel direction relative to horse. Compute angle from horse to panel in horse local space → arm yaw. Simpler: arm just raises and lowers with waving motion, pointing up-forward. The exact pointing is complex; do approximate: compute world angle to active sprite, convert to horse-local yaw, set arm yaw accordingly with lerp. That's doable: \n\n```js\nconst dir = spritePos.clone().sub(horsePos);\nconst worldAngle = Math.atan2(dir.x, dir.z);\nconst local = worldAngle - horseRig.rotation.y;\narmGroup.rotation.y = lerpAngle(armGroup.rotation.y, local, dt*3);\narmGroup.rotation.x = raised pose + wave sin\n```\n\nArm group at shoulder, arm cylinder pointing down by default; to point forward rotate x by ~ -1.4. Add hand sphere.\n\nLeft arm holds reins: static pose, forearm forward. Reins: a line from hand to horse mouth — use THREE.Line or thin cylinder; simpler: two thin cylinders from hands to head area, update endpoints each frame? Use Line with BufferGeometry updated each frame — ok, a simple THREE.Line with 3 points (hand -> middle sag -> mouth), update positions. Actually easier: skip reins or use a static curved tube attached to horse head going to hand region. I'll do a Line updated per frame: point A = left hand world pos, point B = horse mouth world pos, with a mid point sagging. 3-point line fine.\n\nHorse head nodding: head group rotation.x = sin small. Tail sway rotation.z.\n\nEar twitch occasionally: random timer.\n\nRider body slight bounce synced with horse bob; hat stable.\n\nAlso add a \"spotlight\" beam from active concept sprite down? Maybe a soft glowing ring under active sprite: a ring mesh under each sprite, active one glows (emissive intensity high). Or a beacon cylinder of translucent light from sprite to ground for active concept. Nice touch: translucent cylinder (additive) as a light pillar under active sprite. I'll add light pillars under all sprites, only active visible.\n\nGround: big circle geometry, color sage green, with vertex noise? Keep flat but add scattered darker patches (flat circles). Path: torus flat (ring) slightly darker/tan color showing the walking circle — a RingGeometry at radius 5 width 1.2, tan color, just above ground to avoid z-fight (y=0.02).\n\nMountains: 8 big cones at radius 60-80, colors purple-slate, flat shading, some with snow caps (small white cone on top? just cone with different color top — skip, single cones fine, maybe two-tone via second smaller cone).\n\nTrees: trunk cylinder + 2-3 cone layers, scattered radius 12-45, random scale. Also a few cherry-like trees: sphere canopy pink? Golden-hour vibe: orange/pink canopy trees look dreamy. Mix green + autumn orange.\n\nRocks: dodecahedron small, gray.\n\nFlowers: tiny cone stem + sphere top colored, ~60 scattered.\n\nFireflies/particles: Points with additive material, drifting using sin; ~80 within radius 25, height 0.5-5. Warm yellow.\n\nClouds: 6 groups of 3-5 spheres, white, drift slowly, opacity 0.9, at height 20-30, radius 30-55.\n\nSun: big sphere at far, emissive orange, plus a sprite glow (canvas radial gradient). Directional light from same direction.\n\nSky: scene.background gradient — use large sphere with shader or canvas texture. Easiest: canvas 2D vertical gradient texture on BackSide sphere. Or scene.fog + solid color background. I'll do gradient sphere: SphereGeometry(200), MeshBasicMaterial with canvas gradient texture, side: BackSide, fog:false. Colors: top #2b1055 (deep purple), mid #7597de? For golden hour: top #1a2a6c, mid #b21f1f? too red. Let's: top '#241e4e', 55% '#7a4e8f'? Hmm. Sunset: top deep indigo #23205e → #835a9e → #e98a63 → horizon #ffd29d. I'll make gradient stops accordingly.\n\nFog: color matching mid horizon (#e9a06b?), exp2 0.008? With sky sphere unaffected.\n\nLighting:\n- HemisphereLight(skyColor #ffd9b3, ground #4a3b5c, 0.7)\n- DirectionalLight #ffb36b 1.2 from sun direction, castShadow, shadow camera sized ~30.\n\nShadows: horse + rider + trees cast; ground receives. Keep shadow map 2048.\n\nHTML UI styling: glassmorphism card, backdrop-filter blur, rounded, Poppins font, gradient text for title. Progress dots for 10 concepts might crowd; use dots small.\n\nTimer bar on card showing auto-advance progress — nice touch: a thin progress bar animating via CSS width (JS updates).\n\nNow write everything. Watch out for r128 API: \n- `THREE.sRGBEncoding` exists. Set renderer.outputEncoding = THREE.sRGBEncoding for better colors; with CanvasTextures fine.\n- OrbitControls from jsdelivr examples/js works with global THREE.\n\nStructure the script:\n\n```js\nlet scene, camera, renderer, controls, clock;\nlet horseRig, horse parts refs, riderArm..., conceptSprites = [], pillars = [], bubbles\nlet activeIndex = 0, conceptTimer = 0, CONCEPT_INTERVAL = 8;\nlet paused = false, autoRotate = true;\nlet time = 0;\n```\n\nBuild functions: buildEnvironment(), buildHorse(), buildRider(), buildConcepts(), buildBubble().\n\nBubble above rider: sprite with canvas, updated on concept change: draw rounded bubble with tail, text = icon + name. Scale ~ (3.2, 1.6). Position above rider head in horseRig local: add to horseRig at (0, 4.2, 0)? Sprite always faces camera — fine.\n\nBut bubble at fixed local position while horse circles — sprite will face camera; tail pointing down toward head approx ok.\n\nUI update: function setConcept(i): update card with fade (CSS class toggle), update sprites (rebuild textures active/inactive), update pillars visibility, bubble texture redraw, gestureReset (arm raise pulse: set gesturePulse = 1, decays, arm raises when pulse high).\n\nArm raise: armX = base(-0.5 holding reins?) Actually right arm: base relaxed (rot x -0.2 down-ish), on concept change pulse → target -2.4 (raised up pointing). Wave: rotation.z = sin(t*6)*0.15*pulse.\n\nLet me define arm geometry: shoulder group at (±0.45, 1.45, 0) relative rider torso group. Upper arm cylinder from shoulder down length 0.55 → pivot at top: create cylinder translated so top at origin (geometry.translate(0,-0.275,0)). Elbow group at (0,-0.55,0) child of upper arm. Forearm cylinder length 0.5 translated similarly, hand sphere at end.\n\nPoint pose: shoulderGroup.rotation.x = -1.5 raises arm forward horizontal; -2.6 raises up. For pointing toward panel: shoulder.rotation.x = -1.6, plus arm yaw: rotate shoulder parent group rotation.y toward target. I'll wrap shoulder in `armR` group; set armR.rotation.y = localYaw, armR.rotation.x handled by shoulder child? Combined rotations order YXZ fine: set group.rotation.order='YXZ', rotation.y=yaw, rotation.x=-1.6 - pulse*0.6, rotation.z wave.\n\nLeft arm: fixed: rotation.x=-0.9 (holding reins forward-down), elbow bend.\n\nLegs of rider: hip group both sides, thigh rotated forward (sitting), calf down, boot box. Static.\n\nHorse trot bob: body.position.y = baseY + |sin|? Use sin(2*stride) small. Also slight roll.\n\nHorse parts (units): body center y=1.6, body sphere scaled (1.9 length along z? Horse faces +z). I'll orient horse forward = +z. Legs at x=±0.35, z=±0.75. Body: sphere r0.62 scale (1, 1, 1.55)? scale x 0.95, y 1, z 1.7. Neck group at (0, 1.85, 0.85) rotation.x = -0.7? Neck tilts forward-up: cylinder along y translated, group rotated x ≈ -0.9 rad so top leans forward(+z). Head group at neck top (0, 0.75, 0) child of neck; head box (0.34,0.4,0.7) with snout smaller box forward; ears cones on top.\n\nNeck cylinder: radius 0.22 top? Cylinder(0.18, 0.3, 0.9) translate y +0.45. Mane: 4-5 small boxes along back of neck.\n\nLegs: hip/shoulder group at body corners y=1.55? Legs attach at y≈1.5 bottom of body ~1.1. Upper leg cylinder(0.09,0.075,0.6) translate -0.3, group at y 1.35. Knee group y -0.6; lower cylinder(0.06,0.05,0.55) translate -0.275; hoof box at -0.58 (0.14,0.1,0.16). Leg group rotation.x = swing.\n\nGait: front legs phase: FL=sin(φ), FR=sin(φ+π), BL=sin(φ+π+0.3), BR=sin(φ+0.3)? Diagonal: FL & BR together, FR & BL together. φ = time*gaitFreq. swing amplitude 0.5, knee bend = max(0, -sin(phase))*0.8 + 0.15.\n\nSaddle: box rounded (box scaled) brown on body top y 2.15; saddle blanket colored box slightly bigger under.\n\nRider seated: rider group at y ~2.2 on saddle, part of horseRig? Rider should bob with horse — make rider child of horseRig positioned (0, 0, -0.1) with its own y. Actually put rider group as child of horse group so inherits bob? Body bob applied to body mesh only; simpler: apply bob to whole horseRig children except legs? Standard trick: bob the body group containing body+neck+head+rider, legs separate. Structure:\n\nhorseRig (positioned on path, yaw)\n ├─ bodyGroup (bob y, pitch)\n │ ├─ body mesh, neckGroup→head, tail, saddle\n │ └─ riderGroup (rider meshes)\n └─ legs (4 leg groups)\n\nBubble: child of bodyGroup at (0, 4.3, 0)? Bubble should stay readable; ok.\n\nShadow: set castShadow on meshes.\n\nNow the concept ring sprites: create at angle i/N*2π, radius 10, y 4.5 + bob. Pillar: cylinder radius 0.35, height 4.2, y 2.1, material additive transparent opacity 0.25 color concept color; visible only active. Also base ring: RingGeometry radius 0.8 at ground under each, color concept color, opacity 0.5, active → opacity 1 & pulsing.\n\nAlso each sprite has small pole? skip.\n\nsetConcept updates: inactive sprites texture (dark glass style), active sprite texture (bright, glow border), scales: active 1.35x.\n\nSprite texture drawing (inactive): rounded rect rgba(20,16,40,0.75), border 1px rgba(255,255,255,0.25), icon 64px, text 40px bold white. Active: bg gradient concept color translucent, border bright, text white, maybe glow shadow. Canvas 512x256.\n\nEmoji in canvas: fillText emoji works in browsers. Icons: 🎯🗂️🧭🎛️🤝📣🧠⏰🐎🔥 etc.\n\nConcept list finalize (10):\n1. 🎯 Planning — \"Chart the course before the ride. Set clear goals, map the route, and prepare for every fork in the trail.\"\n2. 🧩 Organizing — \"Saddle up the right way. Arrange people, resources, and roles so everything fits and nothing slips.\"\n3. 🧭 Leading — \"Guide, don't force. Great leaders point the way and inspire others to follow, like a steady hand on the reins.\"\n4. 📊 Controlling — \"Check the reins often. Measure progress against the plan, and gently correct course when you drift.\"\n5. 🤝 Delegation — \"Trust your horse to run. Give your team ownership — you can't pull every cart yourself.\"\n6. 📣 Communication — \"Clear signals, clear results. A small, well-timed tug speaks louder than shouting.\"\n7. ⚖️ Decision Making — \"At a fork in the trail, choose. Gather facts fast, decide, and commit — hesitation costs daylight.\"\n8. ⏳ Time Management — \"Pace the journey. Prioritize what matters, or you'll run out of trail before sunset.\"\n9. 🐎 Teamwork — \"Horse and rider move as one. Great teams sync their strides toward a shared destination.\"\n10. 🔥 Motivation — \"The carrot beats the stick. Inspire with purpose and recognition, and people will gallop for you.\"\n\nCard UI: icon, title, description, index \"3 / 10\", prev/next arrows, progress bar. Also small hint bar.\n\nButtons: bottom-right or top-right: Pause/Play ⏸/▶, Camera 🔁 (auto-rotate toggle). Also maybe speed? keep two.\n\nColors for concepts (hex): \nPlanning #ffd166, Organizing #06d6a0, Leading #ef8354, Controlling #118ab2, Delegation #a78bfa, Communication #f472b6, Decision #f4a261, Time #4cc9f0, Teamwork #90be6d, Motivation #ff6b6b.\n\nNow, write the full HTML. Careful with OrbitControls CDN: `https://cdn.jsdelivr.net/npm/three@0.128.0/examples/js/controls/OrbitControls.js` — defines THREE.OrbitControls. Good.\n\nResize handler. Pixel ratio cap 2.\n\nAnimation loop with clock delta; time += dt when not paused (but camera controls always update).\n\nAuto-advance: conceptTimer += dt when !paused; if > INTERVAL → next. Progress bar width = timer/INTERVAL*100%.\n\nManual next/prev: setConcept and timer=0.\n\nsetConcept(i): \n- activeIndex = (i+N)%N\n- update card DOM with small fade animation: card.classList.remove('pop'); void card.offsetWidth; card.classList.add('pop')\n- update dots? I'll include a dots row.\n- update sprites/pillars/rings: for each, redraw texture active or not (rebuild canvas texture: store sprite.userData.index; call drawConceptTexture(ctx...) then texture.needsUpdate).\n- gesturePulse = 1.\n- bubble texture redraw with icon+name.\n\ndrawConceptTexture(canvas, concept, active) helper.\n\nBubble canvas 512x256: white-ish bubble rounded rect with tail triangle bottom center, dark text: icon + name. Also small \"💬\"? just name. Border soft. Bubble sprite scale (2.6, 1.3), position (0, 4.15, 0) as child of bodyGroup; it will swing with bob slightly — fine.\n\nActually the bubble should probably not rotate wildly with horse — it's child so local position fixed relative horse; sprite orientation always camera-facing anyway, so its position rotates around — acceptable, stays above head (x=0 keeps centered above regardless of horse yaw since position (0,y,0) is rotation axis — yes! x=0,z=0 means it stays directly above regardless of yaw. \n\nFireflies: Points geometry positions random; per-frame y offset via sin using stored base positions; use ShaderMaterial? Simple: PointsMaterial size 0.12, color #ffd88a, transparent, additive, depthWrite false. Move whole points cloud rotation.y slowly + individual y via position attribute update each frame (80 points cheap).\n\nClouds drift: each cloud group userData.speed, position.x += speed*dt; wrap at ±70.\n\nCamera initial: (10, 6, 12) target (0,2.2,0). minDistance 4, maxDistance 40, maxPolarAngle 1.5 (avoid under ground), enableDamping.\n\nautoRotate speed 0.8; toggle button sets controls.autoRotate.\n\nAlso add subtle camera... fine.\n\nTitle top-left with gradient text. Hint bottom-left? Put hint in top-right small. Buttons bottom-right. Card bottom-center.\n\nMobile: touch works with OrbitControls. Card width responsive.\n\nLet me write drawRoundRect helper for canvas.\n\nEdge: sRGBEncoding with MeshStandardMaterial colors fine.\n\nFog: scene.fog = new THREE.Fog(0xe8a06a, 40, 140)? Sky sphere radius 200 inside fog range would get fogged (material.fog false for sky). Set skyMat.fog = false.\n\nMountains at radius ~70-95, height 25-40, color #5d4a7a / #6b5b95, with fog they'll blend nicely. Fog end 160.\n\nAlso stars? Sunset, skip.\n\nSun sphere at (-60, 25, -80) color #ffdf9e emissive; sprite glow radial gradient additive scale 40. Directional light position (-40, 30, -50) target origin.\n\nWrite horse coat color: warm brown #8b5a2b, mane/tail darker #5a3a1a, muzzle lighter #c9a37e? Head box same brown with lighter snout box. Hooves dark #3a2a20. Saddle #7a4a21 with blanket #c0392b or teal #0f766e. Rider: shirt #e63946? Let's: jeans #33518a, shirt #f1fa8c? Make rider shirt cream #f4e1c1, vest #8a5a2b, skin #e8b48a, hat #6b4423, dark hair.\n\nTail: group at body back (0, 1.95, -1.05), cone pointing down-back: cylinder(0.05,0.14,0.8) rotated x ~ 0.5; sway rotation.x = 0.5 + sin(t*2)*0.1, rotation.z = sin(t*1.3)*0.15.\n\nEars: cones on head top, twitch: ears.rotation.z = sin(t*7)*0.05 with occasional... keep simple continuous subtle.\n\nHead nod: neck group base rotation.x = -0.95 + sin(t*gait/2)*0.05 + occasional head bob. Also whole head group slight.\n\nGait freq: horse angular speed w = 0.22 rad/s on radius 5.2 → v=1.14 u/s. Stride freq ~ v/0.9 ≈ 1.27 Hz → ω_leg = 2π*1.27 ≈ 8 rad/s. That's fast-ish trot. Use ω_leg = 7.\n\nBob amplitude 0.06 at 2× stride? body bob per stride twice... use sin(φ*2)*0.04 + small.\n\nNow code it all. Also ensure concept ring doesn't collide with walking circle: ring radius 10 > 5.2 ✓.\n\nGround circle radius 90, color #7da05c? Golden hour grass: #6f9a54 warmer #86a860. Use #79a05a. Path ring tan #cbb27a opacity... RingGeometry(4.5, 5.9) color #c9ad72 at y 0.02. Also center small podium circle? Maybe a small round rug at center with star? Add a simple wooden sign near center? Keep center empty since horse circles around it; put a campfire? A campfire center could be cute but horse circles fire weirdly. Put a small pond? skip — center gets a \"POLC\" stone monument! A stone pedestal with rotating golden gear/star on top at center — nice focal point. I'll add pedestal cylinder + torus + rotating icosahedron gold \"management gem\". The gem rotates and bobs. \n\nAlso floating around gem maybe 4 small icons P,O,L,C? Skip, enough.\n\nReins line: horse mouth world pos: get head world position via head.getWorldPosition + offset forward. Left hand world pos similarly. Update line geometry each frame:\npoints: hand, mid(hand+mouth)/2 + down 0.15, mouth. Use BufferGeometry setFromPoints each frame (creates garbage; instead preallocate positions attr and update). Simple: line.geometry.setFromPoints([...]) each frame is fine for 3 points.\n\nActually simpler: two lines (left & right hands to mouth). Keep one.\n\nLet me now write final code. I'll be careful with syntax.\n\n```js\nfunction roundedRect(ctx,x,y,w,h,r){ctx.beginPath();ctx.moveTo(x+r,y);ctx.arcTo(x+w,y,x+w,y+h,r);ctx.arcTo(x+w,y+h,x,y+h,r);ctx.arcTo(x,y+h,x,y,r);ctx.arcTo(x,y,x+w,y,r);ctx.closePath();}\n```\n\nConcept texture draw:\n\n```js\nfunction drawConceptPanel(c, active){\n const cv=document.createElement('canvas');cv.width=512;cv.height=256;const x=cv.getContext('2d');\n x.clearRect(0,0,512,256);\n roundedRect(x,10,10,492,236,36);\n if(active){const g=x.createLinearGradient(0,0,512,256);g.addColorStop(0,hexA(c.color,0.95));g.addColorStop(1,hexA('#1b1640',0.9));x.fillStyle=g;}else{x.fillStyle='rgba(18,14,38,0.78)';}\n x.fill();\n x.lineWidth=active?10:4;x.strokeStyle=active?c.color:'rgba(255,255,255,0.28)';x.stroke();\n x.textAlign='center';\n x.font='90px serif';x.fillText(c.icon,256,120);\n x.font='bold 54px Poppins, Arial';x.fillStyle='#fff';\n // wrap long names: 'Decision Making' length 15 fits at 54px? width ~ 15*30=450 ok.\n x.fillText(c.name,256,205);\n if(active){x.font='30px Poppins';x.fillStyle='rgba(255,255,255,0.75)';x.fillText('★ now explaining ★',256,244);} // y=244 near bottom edge inside 236? rect bottom at 246, text baseline 244 slightly overlapping border; use 240.\n return cv;\n}\n```\n\nHmm \"now explaining\" might clutter; add small tag top-right? Keep: active adds \"▲ LIVE\" no... I'll skip extra text; visual border+scale suffices. Actually add subtle '● ' tag maybe skip.\n\nhexA helper converts hex + alpha to rgba.\n\nBubble draw:\n\n```js\nfunction drawBubble(c){\n cv 512x256; rounded rect (20,10,472,190,40) white rgba(255,255,255,0.95); tail triangle from (236,200) (276,200) (256,246); fill white. border #333? soft gray stroke. text: icon 64px at y 95 center x 120? Layout: icon left, name right? center: icon+name on one line: font bold 52px; measure? simpler: icon above name: icon y 80, name y 160, tail below.\n}\n```\n\nBubble position y 4.35 above rider (rider head ~3.6 with hat). Horse body y bob included via bodyGroup.\n\nText sprite scale: panel inactive (3.4,1.7), active (4.4,2.2) — lerp scale each frame toward target.\n\nStore in conceptSprites[i] = {sprite, pillar, ring, baseScale, targetScale}.\n\nPillar: CylinderGeometry(0.4,0.55,4.4,16,1,true) openEnded, MeshBasicMaterial({color, transparent, opacity:0.22, blending:Additive, side:DoubleSide, depthWrite:false}); visible active only; also pulse opacity 0.18+0.1*sin(t*3).\n\nRing at ground: RingGeometry(0.7,0.95), rotated -π/2, y 0.03, color, opacity 0.35 inactive, 0.95 active + pulse scale.\n\nTrees function:\n\n```js\nfunction makeTree(x,z,s,autumn){\n trunk Cylinder(0.12*s,0.18*s,1.2*s) brown; canopy: 3 cones stacked (green #3f7d44 or autumn #e07840/#d95d39) \n}\n```\n\nScatter 26 trees radius 14–48, avoid path (r>12 ✓), random.\n\nRocks 14, flowers 50 (r 2..44 avoiding path ring 4.3-6.1: if r in [4,6.5] skip).\n\nGrass tufts: 80 small cones green darker, height 0.25, random.\n\nMountains: for i in 10: angle i/10*2π + jitter, r 70+rand25, h 22+rand18, radius 12+rand10, cone 4-5 segments, color lerp purple; snow: smaller white cone on top at h*0.72.\n\nCloud makeCloud(): group of 4-6 spheres flattened (scale y 0.6), MeshStandard white flat? Use MeshBasicMaterial fog:false white opacity 0.85 so they glow against sky. Basic + transparent. Place y 22-34, drift.\n\nFireflies: base positions array; per frame update y = base + sin(t*speed + phase)*0.5, x slight.\n\nGem monument: pedestal cylinder(0.9,1.2,1.2) stone #8d99ae, torus ring gold tilted, icosahedron gold #ffd166 emissive #b8860b metalness high, rotating. y bob. Also a soft point light at gem? PointLight gold 0.6 distance 12 — adds vibe. Yes.\n\nShadow config: dir light shadow camera left/right/top/bottom ±22, near 1 far 120, mapSize 2048.\n\nHorse castShadow all meshes: traverse set.\n\nNow the rider details:\n\nriderGroup at (0, 2.02, -0.05) in bodyGroup (body center y 1.6, top ~2.2; saddle at 2.15; rider hips at 2.2). Let me set riderGroup origin at hip point y=2.18.\n\n- hips box (0.5,0.25,0.35) jeans\n- torso group at y+0.15: box(0.52,0.62,0.34) shirt; slight lean forward rotation.x 0.08\n- head group at y 0.95 (relative riderGroup): sphere r 0.24 skin; hair cap: sphere half darker on back? use slightly bigger sphere scaled flattened at top-back... simple: hat covers: brim cylinder r0.42 h0.05, dome sphere r0.26 scaled y0.7 on top, hat color #6b4423. Add eyes? tiny spheres black front — nice detail: two 0.03 spheres at front of head. And a smile? skip.\n- scarf/bandana red small torus? skip.\n- legs: hipL group at (0.18, 0.05, 0.05)... rider sits: thigh goes forward-down angled: rotation.x = -1.5? Let's define leg pivot at hip: thigh cylinder down length 0.45, rotate x -1.2 (forward) and z ±0.5 (straddle out). calf group at thigh end, rotation.x = 1.3 (down). boot box. Stirrup? skip.\n- arms as planned; left arm pose static holding rein; right arm gesture.\n- Also a lasso or stick? skip.\n\nRight arm rest pose: rotation.x = -0.35 (slightly forward). Gesture: when pulse>0, raise: targetX = -0.35 - pulse*1.9 → up to -2.25 (pointing up-forward). yaw toward active panel: armYawTarget computed; blend weight pulse (so when relaxed arm returns center).\n\nWave: rotation.z = sin(time*7)*0.25*pulse.\n\npulse decays: gesturePulse = max(0, pulse - dt*0.4) → ~2.5s gesture. Also each frame recompute yaw target from active sprite world pos.\n\nWorld positions: active sprite position known: ringPos[i] fixed (they bob y slightly). horseRig.position known, horseRig.rotation.y known. local yaw = atan2(dx, dz) - horseYaw. Arm forward is +z when rotation.y=0? Shoulder group in rider space: forward +z. Yes horse faces +z.\n\nNote: rider might face +z same as horse. Yes.\n\nNormalize angle to [-π,π].\n\nAlso head look: head group rotation.y = localYaw*0.5*pulse — rider looks where pointing. \n\nBubble tail points down center — fine.\n\nCard fade CSS: .pop animation scale 0.96→1 opacity.\n\nDots: 10 dots; active dot colored with concept color & wider.\n\nButtons style: glass round.\n\nNow assemble HTML. Also loading overlay? Not needed; quick.\n\nAlso add keyboard arrows to switch concepts. Nice.\n\nLet me write the final code in one block. Also meta viewport for mobile.\n\nDouble-check OrbitControls r128: `controls = new THREE.OrbitControls(camera, renderer.domElement)` ✓ damping ✓ autoRotate ✓.\n\nOne concern: jsdelivr three@0.128.0 examples/js controls depends on nothing else ✓.\n\nEmissive + sRGBEncoding fine.\n\nFont Poppins link: plus preconnect.\n\nProgress interval 8s.\n\nPause button toggles `paused`; when paused: time frozen (no animation updates), concept timer frozen, gem rotation frozen; controls still work. Button label ▶/⏸.\n\nAuto button toggles controls.autoRotate; label 🔁 with active class.\n\nWrite code now, mentally compile for errors.\n\nHorse build detail code:\n\n```js\nfunction buildHorse(){\n horseRig = new THREE.Group(); scene.add(horseRig);\n bodyGroup = new THREE.Group(); horseRig.add(bodyGroup);\n const coat = new THREE.MeshStandardMaterial({color:0x8b5a2b, flatShading:true, roughness:0.9});\n const dark = new THREE.MeshStandardMaterial({color:0x4a3018, flatShading:true, roughness:0.95});\n // body\n const body = new THREE.Mesh(new THREE.SphereGeometry(0.72, 10, 8), coat);\n body.scale.set(1, 1.02, 1.75); body.position.y = 1.62; bodyGroup.add(body);\n // chest & rump for shape\n const chest = sphere r0.5 at (0,1.6,0.75) scale(1,1,1)\n const rump = sphere r0.55 at (0,1.66,-0.7)\n // neck\n neckGroup = new THREE.Group(); neckGroup.position.set(0, 1.9, 0.95); bodyGroup.add(neckGroup);\n const neck = new THREE.Mesh(new THREE.CylinderGeometry(0.17, 0.30, 1.05, 7), coat);\n neck.geometry.translate(0, 0.5, 0); neckGroup.add(neck);\n neckGroup.rotation.x = -0.85; // lean forward... \n```\n\nWait rotation.x negative rotates top toward +z? Rotating around x axis by -0.85: positive y axis tilts toward +z when rotation.x is positive? Rotation about X by θ maps +Y to (0, cosθ, sinθ). So +θ tilts top toward +z. Horse faces +z, neck should lean forward → rotation.x = +0.85? Let me verify: R_x(θ): y' = y cosθ - z sinθ; z' = y sinθ + z cosθ. Point (0,1,0) → (0, cosθ, sinθ). θ=0.85 → z=+0.75 yes top goes forward. So neckGroup.rotation.x = 0.75 (mostly upright leaning forward).\n\nHead group at (0, 1.05, 0) child of neck; head rotated slightly: rotation.x = -0.75+? Head should be roughly horizontal: head mesh box aligned along z. headGroup.rotation.x = -0.9 relative neck → net head orientation: neck(0.75) + head(-0.95) = -0.2 slight down — head forward slightly down. Fine-tune: headGroup.rotation.x = -1.0.\n\nHead: box(0.34, 0.42, 0.55) at headGroup origin-ish (0, 0.05, 0.15)? Place head box center (0,0,0.1); snout box(0.24,0.28,0.4) at (0,-0.08,0.5) color lighter #a67c4f; nostrils skip. Ears: cones r0.06 h0.18 at (±0.11, 0.28, -0.05). Eyes: spheres 0.035 dark at (±0.14, 0.08, 0.28).\n\nMane: boxes (0.07, 0.18, 0.22) dark along neck back edge: positions along neck local: neck top toward back = local -z side... After neck rotation, mane sits on the back (upper-rear edge). Place mane boxes as children of neckGroup at (0, 0.25+i*0.2, -0.16 - i*0.02) for i 0..4, dark color. Slight rotate same. Fine — they're children so they follow.\n\nTail: tailGroup at (0, 2.05, -1.15) child of bodyGroup; tail cylinder(0.05, 0.16, 0.9, 6) dark, geometry translate(0,-0.4,0) so pivot top; rotation.x = 0.5 base.\n\nLegs: positions (±0.34, 1.35, ±0.72). upper cylinder(0.10,0.08,0.6,7) translate(0,-0.3,0); knee group at (0,-0.6,0); lower cylinder(0.07,0.05,0.55,7) translate(0,-0.275,0); hoof box(0.15,0.12,0.2) at (0,-0.57,0.02) dark. legs cast shadows.\n\nSaddle: blanket box(0.95, 0.08, 1.05) color teal #0e7c7b at y 2.22; saddle box(0.6, 0.14, 0.7) #7a4a21 at y 2.3 with slight rotation? flat ok. Add cantle small box back. Fine.\n\nriderGroup position (0, 2.32, -0.05) child bodyGroup.\n\nRider meshes as planned; hips at origin: hips box y 0.02. Torso group y 0.14. Torso box center y 0.31 (height 0.62). Head group y 0.78: head sphere r0.23 y 0.12? Let me set headGroup at torsoGroup? Simply riderGroup children:\n- hips (0, 0, 0)\n- torsoGroup (0, 0.12, 0): torso box center (0,0.33,0); arms attached at torsoGroup (±0.33, 0.52, 0); head group (0, 0.72, 0): sphere (0,0.14,0) r 0.23; hat brim (0,0.3,0) cylinder(0.4,0.4,0.05); dome sphere r 0.22 scale y 0.75 at (0,0.36,0); eyes (±0.08, 0.16, 0.2).\n\nArms: shoulderR group at (0.33, 0.55, 0) in torsoGroup, order YXZ. upperArm cylinder(0.07,0.06,0.5) translate(0,-0.25,0) shirt color; elbow group (0,-0.5,0); forearm cylinder(0.055,0.05,0.45) translate(0,-0.225,0) skin; hand sphere 0.08 at (0,-0.48,0).\n\nLeft arm: shoulderL.rotation.x = -0.85, elbowL.rotation.x = -0.5. Hand ends forward-ish holding rein.\n\nRight arm rest: shoulderR.rotation.x = -0.3.\n\nLegs: hipR group (0.16, 0.02, 0.02), rotation.x = -1.35, rotation.z = -0.55? Straddle outward: rotation.z for right leg (x positive side) rotate negative? Rotation.z positive rotates +y toward +x? R_z(θ): x' = x cosθ - y sinθ. Point (0,-1,0) (thigh down) with θ=+0.5 → x' = +sin0.5 → moves +x outward for right side ✓. So hipR.rotation.z = 0.5? Wait thigh direction down (0,-1,0): x' = -(-1) sinθ = +sinθ ✓ outward for right leg when θ>0. Left leg θ=-0.5.\n\nthigh cylinder(0.09,0.08,0.45) translate(0,-0.225,0) jeans; kneeR group (0,-0.45,0) rotation.x = 1.5 (calf hangs down after thigh forward); calf cylinder(0.07,0.06,0.4) translate(0,-0.2,0); boot box(0.12,0.1,0.26) at (0,-0.42,0.05) dark.\n\nThigh rotation.x = -1.3 (forward); knee +1.3 → calf near vertical down. ok tweak -1.25/1.35.\n\nReins line from handL to mouth. mouthWorld: compute via headGroup? I have snout; use headMesh.getWorldPosition then add forward offset transformed... simpler: use a dedicated object3D `mouthAnchor` child of headGroup at (0,-0.05,0.7). And handAnchorR/L child of forearm at (0,-0.5,0). Use handL anchor. Update line pts each frame.\n\nLine material color 0x3a2a1a. \n\nAlso horse breathing: body scale pulse tiny: body.scale.y = 1.02 + sin(t*1.2)*0.01. Eh skip.\n\nPath radius R_PATH = 5.2; horse angular speed 0.21.\n\nPer-frame horse update (when !paused):\n\n```js\ntime += dt;\nhorseAngle = time * 0.21;\nhorseRig.position.set(Math.cos(horseAngle)*R, 0, Math.sin(horseAngle)*R);\n// facing tangent: direction of motion = (-sin, 0, cos) → yaw = atan2(dx,dz)= atan2(-sin, cos) = -horseAngle\nhorseRig.rotation.y = -horseAngle + 0; // check: at angle0 pos (R,0,0), moving dir d/dt(cos,sin)=(-sin,cos)=(0,1) → +z; yaw for facing +z is 0 ✓ -angle=0 ✓\nconst stride = time * 7;\nlegFL.rotation.x = Math.sin(stride)*0.55;\nlegBR.rotation.x = Math.sin(stride)*0.55;\nlegFR.rotation.x = Math.sin(stride+Math.PI)*0.55;\nlegBL.rotation.x = Math.sin(stride+Math.PI)*0.55;\nknees: kneeFL.rotation.x = Math.max(0, -Math.sin(stride))*0.9 + 0.1; etc matching phases.\nbodyGroup.position.y = Math.abs(Math.sin(stride))*0.05? trot bob: sin(2*stride)*0.03; use Math.sin(stride*2)*0.035;\nbodyGroup.rotation.z = Math.sin(stride)*0.03;\nneckGroup.rotation.x = 0.75 + Math.sin(stride*1)*0.04;\nheadGroup extra nod: headGroup.rotation.x = -1.0 + Math.sin(stride+1.2)*0.06;\ntail sway...\n```\n\nBubble: child of bodyGroup at (0, 4.6, 0)? rider hat top ~ 2.32+0.12+0.72+0.36+0.15 ≈ 3.67. Bubble at 4.5 center, scale (2.7,1.35) → bottom edge ~3.82 close above hat ✓. Horse ears ~ neck top... head top y ~? neck base 1.9 + up 1.05 mostly vertical → ~2.9 + ears. Bubble at x=0 z=0 above saddle fine.\n\nBubble slight float: bubble.position.y = 4.5 + sin(time*1.5)*0.06; also bubble scale pulse on concept change (pulse).\n\nGem update: rotation.y += dt; y = 1.6+sin*0.1; ring rotation.x slow.\n\nNow concept ring update each frame: sprites bob y = baseY + sin(time*1.2 + i)*0.15; scale lerp: spr.scale lerp toward target (active? big: normal); pillar opacity pulse; ring pulse.\n\nConcept world pos for arm yaw: sprite.position (they're direct children of scene, positions fixed except bob).\n\nsetConcept also: pulse=1.\n\nArm update each frame:\n\n```js\ngesturePulse = Math.max(0, gesturePulse - dt*0.35);\nconst p = easeOut(gesturePulse) // just use p\n// yaw target\nconst sp = conceptSprites[activeIndex].sprite.position;\nconst dx = sp.x - horseRig.position.x, dz = sp.z - horseRig.position.z;\nlet yaw = Math.atan2(dx, dz) - horseRig.rotation.y;\nyaw = Math.atan2(Math.sin(yaw), Math.cos(yaw));\nshoulderR.rotation.y += (yaw*p - shoulderR.rotation.y) * Math.min(1, dt*5);\nshoulderR.rotation.x = -0.3 - p*1.9 + Math.sin(time*6)*0.12*p;\nshoulderR.rotation.z = Math.sin(time*5)*0.15*p;\nelbowR.rotation.x = -0.3 - p*0.3;\nheadGroupR? riderHead.rotation.y = yaw*0.35*p;\n```\n\nWhen p→0 arm returns to -0.3 x, yaw →0. ✓\n\nAlso when paused, skip all time-based updates but still render & controls.update.\n\nConcept timer & progress bar: in animate, if !paused: conceptTimer += dt; if >= INTERVAL: setConcept(active+1); progressBar.style.width = (conceptTimer/INTERVAL*100)+'%';\n\nManual nav resets conceptTimer=0.\n\nButtons wiring; keyboard ArrowLeft/Right.\n\nDots: create spans; update active class & color.\n\nNow finalize HUD copy:\nTitle: \"🐎 The Horseback Mentor\" subtitle \"360° Management Concepts Arena\".\nHint: \"🖱️ Drag to orbit · Scroll to zoom · ← → switch concepts\".\n\nCard:\n```\n

\n```\n\nStyle: glass dark, blur, border 1px rgba white .15, radius 20px, max-width 560px, bottom 24px centered. Icon big 44px in colored rounded square (bg concept color translucent). Title gradient? Title color concept color. Desc 13px rgba(255,255,255,.8).\n\nButtons top-right stacked or bottom-right: `#tools {position:fixed; top:16px; right:16px;}` with pause & rotate buttons + hint below.\n\nTitle top-left.\n\nEverything in one HTML block. Also small footer credit? skip.\n\nEdge: emoji in canvas font: use '90px \"Segoe UI Emoji\", \"Noto Color Emoji\", serif' — plain fillText(emoji) works regardless of font mostly.\n\nAlso, to make panels readable, set sprite.material.depthTest true fine.\n\nFireflies PointsMaterial size 0.15 sizeAttenuation.\n\nSky gradient canvas:\n\n```js\nconst c=document.createElement('canvas');c.width=16;c.height=512;const g=c.getContext('2d');\nconst gr=g.createLinearGradient(0,0,0,512);\ngr.addColorStop(0,'#1b1b4d');gr.addColorStop(0.35,'#4b3a7a');gr.addColorStop(0.62,'#a35d8f');gr.addColorStop(0.8,'#e8806b');gr.addColorStop(1,'#ffd29d');\n```\n\nSphere(220, 24, 16) BackSide MeshBasicMaterial map fog:false. Map on sphere: gradient maps top→bottom with v... sphere UV v=0 at bottom? For SphereGeometry, v=0 at top? In three, uv v goes 0 at top? Actually v=0 corresponds to phi start (top). I believe v=0 at top pole, v=1 bottom. Gradient canvas y=0 top → texture v... textures v=0 at bottom of canvas (flipY default true → canvas top = v=1). With flipY true, canvas row 0 (top) maps to v=1 (bottom of sphere) → inverted. To avoid confusion just test mentally once: I'll set gradient reversed so horizon color appears at equator either way — make gradient symmetric-ish: top dark → horizon warm at ~75%. If flipped, warm appears near top — bad. Safer: build sky with ShaderMaterial? Overkill. Alternative: use scene.background = gradient canvas texture? That stretches to screen — actually scene.background with Texture fills screen as background image — gradient vertical on screen always correct & independent of camera! That works and is simplest: scene.background = canvasTexture with vertical gradient. It won't move with camera (fine, like skybox gradient). But at low camera angles, ground circle radius 90 + fog covers bottom. Set fog color to horizon #e8806b-ish so blend works. Do that — simpler & robust.\n\nAlso renderer clear via background texture handles it.\n\nSun: place sprite glow low near horizon direction matching light.\n\nGround: CircleGeometry(95, 48) rotated -π/2, color #7c9a52... golden-hour grass maybe #8a9a4e warm. Use 0x82a05a with roughness 1, flatShading irrelevant on flat circle.\n\nAdd subtle vertex bumps? skip.\n\nFog: new THREE.Fog(0xdf9b73, 45, 160)? Fog also affects mountains nicely. But fog vs background mismatch at horizon: background gradient bottom is #ffd29d warm; fog color pick #e8a178.\n\nMountains color pick #6a5583 with fog blending.\n\nCheck right: CircleGeometry + fog ok.\n\nClouds MeshBasicMaterial({color:0xffe3c9, transparent, opacity:0.85, fog:false}) — warm-tinted clouds matching sunset. \n\nAlright — also a soft ambient: AmbientLight 0x604a6a 0.5? Hemisphere covers it.\n\nShadows: only dir light casts. Trees/rocks/horse/rider/gem cast; ground receives; mountains far outside shadow cam — fine (castShadow false for mountains to save).\n\nLet me also cap: renderer.setPixelRatio(Math.min(devicePixelRatio, 2)).\n\nNow write out. Also `hexA(hex, a)`:\n\n```js\nfunction hexA(hex,a){const n=parseInt(hex.slice(1),16);return `rgba(${n>>16&255},${n>>8&255},${n&255},${a})`;}\n```\n\nConcept colors as '#ffd166' strings.\n\nDots colors set style.background when active else rgba white .25.\n\nAlso add click on concept sprite to select? Raycaster on sprites: nice extra — implement: pointerdown→ if not dragged... complexity with orbit drag. Skip; buttons + keys enough. Actually simple: on 'click' with small movement check — skip to keep robust.\n\nLet me count UI ids and wire them.\n\nAlso the LIVE indicator: active panel texture gets thicker border + glow shadowBlur:\n\n```js\nif(active){x.shadowColor=c.color;x.shadowBlur=30; stroke after shadow}\n```\n\nApply shadow on the stroke pass.\n\nBubble draw:\n\n```js\nfunction drawBubble(c){\n const cv=document.createElement('canvas');cv.width=512;cv.height=256;const x=cv.getContext('2d');\n x.clearRect(0,0,512,256);\n x.fillStyle='rgba(255,252,245,0.97)';\n roundedRect(x,14,10,484,182,42);x.fill();\n // tail\n x.beginPath();x.moveTo(226,190);x.lineTo(286,190);x.lineTo(256,248);x.closePath();x.fill();\n x.strokeStyle=hexA(c.color,0.9);x.lineWidth=8;roundedRect(x,14,10,484,182,42);x.stroke();\n x.textAlign='center';\n x.font='72px serif';x.fillText(c.icon,120,128);\n x.font='800 56px Poppins, Arial';x.fillStyle='#2a2140';\n // fit name: measure, shrink if wide\n let fs=56;x.font=`800 ${fs}px Poppins, Arial`;\n while(x.measureText(c.name).width>330&&fs>28){fs-=4;x.font=`800 ${fs}px Poppins, Arial`;}\n x.fillText(c.name, 300, 120);\n x.font='600 30px Poppins, Arial';x.fillStyle=hexA(c.color,1)... color text? '#8a7aa8';\n x.fillText('management concept',300,162);\n return cv;\n}\n```\n\nHmm tail overlaps rounded rect bottom (rect bottom at 192; tail from y190). Slight overlap ok (same fill). Stroke of rect bottom edge will show through tail — minor; acceptable, or skip rect stroke. Keep stroke, looks like outline; tail unstroked — fine.\n\nBubble texture: needsUpdate on change. Create once with canvas, reuse redraw.\n\nSame for panels: create each with own canvas + texture; redraw active/inactive on change.\n\nPanel draw refine with icon bg circle:\n\nok writing final answer now. Also add `pop` keyframes, `.glass` etc.\n\nOne more: OrbitControls target (0, 2.4, 0); camera pos (11, 6.5, 13).\n\nINTERVAL = 9.\n\nPause stops: time accumulation; since all animation derived from `time` and dt-driven pieces (clouds, fireflies use time; gesture uses dt — gate with paused). Concept timer gated.\n\nAuto-rotate continues while paused — acceptable (camera independent).\n\nWrite the code:\n\nAlso remember to include both CDN scripts in head, full HTML single block.\n\nPotential pitfall: Poppins in canvas — font may not be loaded when first drawn; panels drawn at init might fall back to Arial — acceptable; could redraw after document.fonts.ready. Add: document.fonts.ready.then(()=>{redrawAllPanels(); redrawBubble();}); nice.\n\nImplement redrawAllPanels(): loop conceptSprites draw into existing canvas & texture.needsUpdate.\n\nStructure sprite objects: {spr, cv, tex, pillar, ring, i, baseY}.\n\nPanel canvas 512x256; sprite scale aspect 2:1 → inactive (3.6,1.8), active (4.6,2.3).\n\nRing positions angle: start offset so concept 0 in front of camera start? whatever.\n\nAlso pillar height 4.4 center y 2.2; sprite baseY 4.9.\n\nRing under: y 0.035.\n\nRing color material MeshBasicMaterial transparent.\n\nAlso center gem: gold icosahedron r0.55 detail 0, MeshStandardMaterial({color:0xffd166, metalness:0.85, roughness:0.25, emissive:0x7a5a10, flatShading:true}); pedestal Cylinder(0.7,1.0,1.1,8) stone #9aa0b0 flat; torus (0.8, 0.07) gold tilt rotation.x=1.2 at y 1.6 spinning around gem. PointLight 0xffd166 0.7 dist 14 at (0,2,0).\n\nPath torus? RingGeometry(4.35, 6.05, 64) color 0xcbb083 opacity 0.9 transparent, y 0.02, receiveShadow. Plus dashed inner? fine.\n\nAlso add faint outer ring at radius 10 under sprites? Each sprite has own ring.\n\nGrass tufts: InstancedMesh would be optimal; 80 separate cones ok too — but perf fine. Use InstancedMesh? Simplicity: loop creating meshes — 80 meshes + 26 trees(3-4 meshes each ~100) + rocks 14 + flowers 50*2=100 → ~350 meshes, fine for low-poly.\n\nMerge? skip, fine.\n\nFinal check on render loop pseudo:\n\n```js\nfunction animate(){\n requestAnimationFrame(animate);\n const dt = Math.min(clock.getDelta(), 0.05);\n if(!paused){\n time += dt;\n updateHorse(dt);\n updateConceptRing(dt);\n updateEnvironment(dt); // clouds, fireflies, gem\n gesturePulse = Math.max(0, gesturePulse - dt*0.35);\n updateArmAndBubble(dt);\n conceptTimer += dt;\n if(conceptTimer >= INTERVAL){ setConcept(activeIndex+1); }\n bar.style.width = (conceptTimer/INTERVAL*100)+'%';\n }\n controls.update();\n renderer.render(scene,camera);\n}\n```\n\nupdateArm uses current gesturePulse even paused? skip when paused (frozen fine).\n\nEverything gated — but arm lerp uses dt; frozen ok.\n\nAlso bubble float uses time ✓.\n\nNow write it all out carefully. I'll aim for clean, complete code.\n\nAdditional: hint element small glass. Title uses gradient text css.\n\nAlso handle context: THREE r128 + CanvasTexture encoding: set tex.encoding = THREE.sRGBEncoding for sprites to look right.\n\nLet me write the final file.\n\nAlso horseAngle initialized so horse starts near camera-ish: time=0 → pos (5.2,0,0). fine.\n\nI'll write updateHorse with all refs stored globally: legs = {FL:{hip,knee},...}, neckGroup, headGroup, tailGroup, bodyGroup, horseRig, riderHead, shoulderR, elbowR, bubble, bubbleCtx/tex/cv.\n\nRein line: create geometry with 3 points positions Float32Array(9); update:\n\n```js\nhandAnchorL.getWorldPosition(v1); mouthAnchor.getWorldPosition(v2);\nmid = v1+v2 /2, y -= 0.18;\npositions.set([...]) attr.needsUpdate = true;\n```\n\nUse temp vectors to avoid alloc: preallocate THREE.Vector3s.\n\nLine is child of scene (world coords) ✓.\n\nOk also horse cast/receive: traverse horseRig set castShadow true (sprites excluded—bubble is sprite; Sprite has castShadow? Setting castShadow on sprite might warn? It's Object3D property, harmless).\n\nSet on meshes only via `if(o.isMesh)`.\n\nAlso ground receiveShadow true; path receive.\n\nTrees cast shadows: yes each mesh.\n\nAlright, writing now. Also include small “LIVE” tag: active panel extra text \"— LIVE —\"? I'll add small '● EXPLAINING' top of active panel:\n\nIn drawConceptPanel active: font 28px Poppins fillStyle white alpha .85, text '● NOW EXPLAINING' at y 52 (above icon). Icon y 128, name y 208. Adjust: icon 78px at y 130; name 50px bold at y 208.\n\nLet me finalize panel layout:\n- rect (10,10,492,236,r36)\n- active tag y 54\n- emoji y 132 (font 80px)\n- name y 206 (font bold 48px, shrink to fit 430)\n\nBubble layout as above.\n\nCSS: \n\n```css\n*{margin:0;padding:0;box-sizing:border-box}\nhtml,body{height:100%;overflow:hidden;font-family:'Poppins',sans-serif;background:#1b1b4d}\ncanvas{display:block}\n#title{position:fixed;top:18px;left:20px;color:#fff;z-index:5;pointer-events:none}\n#title h1{font-size:22px;font-weight:800;background:linear-gradient(90deg,#ffd166,#ff8fa3,#a78bfa);-webkit-background-clip:text;background-clip:text;color:transparent}\n#title p{font-size:11px;color:rgba(255,255,255,.65);letter-spacing:.18em;text-transform:uppercase}\n#tools{position:fixed;top:16px;right:16px;display:flex;gap:8px;z-index:6}\n.tbtn{...glass circle 42px...}\n.tbtn.on{outline:2px solid #ffd166;}\n#hint{position:fixed;right:16px;top:66px;font-size:10.5px;color:rgba(255,255,255,.55);text-align:right;z-index:5;pointer-events:none}\n#card{position:fixed;left:50%;bottom:20px;transform:translateX(-50%);width:min(580px,92vw);background:rgba(17,13,34,.62);backdrop-filter:blur(14px);border:1px solid rgba(255,255,255,.14);border-radius:20px;padding:14px 16px 18px;display:flex;gap:14px;align-items:center;z-index:6;color:#fff;box-shadow:0 12px 40px rgba(0,0,0,.35)}\n#card.pop{animation:pop .45s ease}\n@keyframes pop{0%{transform:translateX(-50%) scale(.96);opacity:.4}100%{transform:translateX(-50%) scale(1);opacity:1}}\n#cIcon{font-size:30px;width:60px;height:60px;display:flex;align-items:center;justify-content:center;border-radius:16px;flex:0 0 auto}\n#cTitle{font-weight:800;font-size:18px}\n#cDesc{font-size:12.5px;line-height:1.45;color:rgba(255,255,255,.78);margin-top:2px}\n.cBody{flex:1;min-width:0}\n.cFoot{display:flex;align-items:center;gap:10px;margin-top:8px}\n#cNum{font-size:10.5px;color:rgba(255,255,255,.5);letter-spacing:.1em}\n#dots{display:flex;gap:5px}\n#dots i{width:6px;height:6px;border-radius:99px;background:rgba(255,255,255,.22);transition:all .3s}\n.nav{display:flex;flex-direction:column;gap:6px}\n.nav button{width:34px;height:34px;border-radius:12px;border:1px solid rgba(255,255,255,.18);background:rgba(255,255,255,.08);color:#fff;font-size:18px;cursor:pointer}\n.nav button:hover{background:rgba(255,255,255,.18)}\n#bar{position:absolute;left:16px;right:16px;bottom:8px;height:3px;border-radius:99px;background:rgba(255,255,255,.12);overflow:hidden}\n#bar i{display:block;height:100%;width:0;background:linear-gradient(90deg,#ffd166,#ff8fa3);border-radius:99px}\n```\n\nNav buttons horizontal might be better; vertical column ok.\n\ncIcon background set via JS hexA(color,0.25) + border.\n\nButtons: \n\n```html\n

It should be:\n- 3D with 360-degree movable camera\n- Animated (man on horse)\n- Educational content about management concepts\n- \"Vibe coded\" - meaning stylish, aesthetic, engaging\n\nI'll use Three.js to create this. Let me plan:\n\n1. **Scene setup**: A nice environment - maybe a stylized low-poly world with ground, sky, trees, sun\n2. **Horse**: Built from primitives (boxes, cylinders, spheres) - body, head, legs, tail, mane. Animated with leg movement, head bobbing, tail sway\n3. **Man/Rider**: Sitting on horse - body, head, arms that gesture (like explaining), maybe a pointing gesture animation\n4. **Management concepts**: Floating 3D text/panels showing concepts like:\n - Leadership\n - Planning\n - Organizing\n - Leading\n - Controlling (POLC framework)\n - Communication\n - Delegation\n - Teamwork\n - Time Management\n - Decision Making\n \n5. **Speech bubble / info panel**: Shows the current concept being explained\n6. **OrbitControls**: For 360-degree camera movement\n7. **Animation loop**: Horse idle animation, rider gesturing, floating concept icons rotating around\n\nLet me build this carefully:\n\n- Use Three.js from CDN (use a version that works with OrbitControls from CDN). I'll use the older style with script tags:\n - `https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js`\n - `https://cdn.jsdelivr.net/npm/three@0.128.0/examples/js/controls/OrbitControls.js`\n\n- Low-poly aesthetic with flat shading\n- Nice gradient sky\n- Fog for depth\n- Trees (cone + cylinder)\n- Clouds (groups of spheres)\n- Sun with glow\n\nHorse construction:\n- Body: stretched box or capsule\n- Neck: angled box\n- Head: box\n- Ears: small cones\n- Legs: cylinders with lower legs\n- Tail: curved\n- Mane: boxes along neck\n\nAnimation:\n- Legs trot in diagonal pairs (like walking gait)\n- Body bobbing\n- Head nodding\n- Tail swaying\n- Rider arm gestures - rotating arm up/down as if explaining\n- Occasionally the horse moves in a circle? Or stays in place? Maybe the horse walks slowly in a circle around a central area - that would be cool with 360 camera. Actually, let me make the horse walk in a circular path so there's movement.\n\nManagement concepts display:\n- Rotating ring of concept panels around the horse, OR\n- A \"podium\"/holographic board in front, OR\n- Floating text sprites that cycle\n\nI'll do: floating holographic panels arranged in a circle around the center, each with a concept name. The current concept gets highlighted and a big speech bubble (HTML overlay or 3D sprite) shows the explanation.\n\nActually a nice approach: HTML UI overlay with:\n- Title\n- Concept card that cycles every ~6 seconds with concept name + description\n- Controls hint\n- Buttons to navigate concepts\n\nPlus 3D floating text sprites around the scene.\n\nFor 3D text, I can use canvas textures on planes - easier than TextGeometry with font loading.\n\nLet me code:\n\n```html\n\n\n\n\nManagement Wisdom — The Horseback Mentor\n\n\n\n\n\n
