Parallax Depth
Three depth layers of glowing motes float upward with a gentle sine sway. Distant motes are small, soft and slow while near ones are large, sharp and fast, and the layers shift by depth as you move the cursor for a real sense of parallax.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Parallax Depth".
Description: Three depth layers of glowing motes float upward with a gentle sine sway. Distant motes are small, soft and slow while near ones are large, sharp and fast, and the layers shift by depth as you move the cursor for a real sense of parallax.
Current settings: count = 60, depth separation = 1, drift = 1, color = Single, hue = 210, second hue = 290.

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.
