Blob Simulation

Prompt

Build a fullscreen interactive gelatinous blob simulation in a single HTML file using Canvas and JavaScript. The blob should feel alive and organic — a soft, translucent, amorphous mass that constantly wobbles, breathes, and deforms on its own. Use a ring of spring-connected control points around a soft-body center, driven by Perlin or simplex noise so the surface ripples naturally. Layer in a slow "breathing" oscillation that expands and contracts the whole body. Render with radial gradients, semi-transparency, and a subtle inner glow so it looks wet and gelatinous — think slime mold or a jellyfish bell. Add 2–3 smaller internal "organelle" blobs that drift lazily inside, slightly out of phase. On mouse hover the blob should bulge toward the cursor like it's curious; on click it should squish dramatically then jiggle back. Apply subtle ambient drift so it slowly roams the canvas. Use requestAnimationFrame for smooth 60fps animation. No external libraries — vanilla JS only. Dark background with a faint vignette. The entire vibe should be "this thing is alive."
