Black Hole
A dark void ringed by a glowing event horizon, fed by a spiraling accretion disk that orbits faster and stretches into streaks as it's pulled inward. Click to inject a burst of matter that spirals in.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Black Hole".
Description: A dark void ringed by a glowing event horizon, fed by a spiraling accretion disk that orbits faster and stretches into streaks as it's pulled inward. Click to inject a burst of matter that spirals in.
Current settings: particles = 700, pull = 1, spin = 1, disk size = 0.8, streak = 0.5, color = Dual, hue = 30, 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.
