Aurora Veil
Flowing aurora curtains that wave and shimmer over a faint starfield, pulsing with an internal rhythm for an audio-reactive feel. Move to bend the nearest curtain; click to send a pulse rippling along the veil.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Aurora Veil".
Description: Flowing aurora curtains that wave and shimmer over a faint starfield, pulsing with an internal rhythm for an audio-reactive feel. Move to bend the nearest curtain; click to send a pulse rippling along the veil.
Current settings: curtains = 4, wave speed = 1, height = 0.8, shimmer = 0.5, brightness = 1, color = Single, hue = 150, second hue = 280.

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.
