Particle Morph
A point cloud of thousands of particles that smoothly morphs between a sphere, cube, torus, and cone on a loop, with a gentle idle swirl. Click to jump to the next shape.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Particle Morph".
Description: A point cloud of thousands of particles that smoothly morphs between a sphere, cube, torus, and cone on a loop, with a gentle idle swirl. Click to jump to the next shape.
Current settings: particles = 6000, morph speed = 1, auto morph on, point size = 0.06, color = Dual, hue = 280, second hue = 180.

Requirements:
- Use requestAnimationFrame with a delta-time (dt) step, clamped to avoid jumps on tab switches.
- Render crisply: fully clear the canvas every frame (clearRect). Do NOT fake motion blur by painting a translucent background each frame, because that causes permanent 8-bit "ghost" burn-in. If you want trails, store each particle's recent positions and draw them as an explicit fading tail.
- If many short-lived particles are spawned, use an object pool (pre-allocate, reuse, swap-remove on death) to avoid GC pauses.
- Scale the backing store by devicePixelRatio (cap ~2) and handle resize.
- Pause when the tab is hidden or the canvas is off-screen; respect prefers-reduced-motion.
- Expose the listed settings as adjustable props/controls.
