Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Corner Fireworks".
Description: Fountain cannons in the corners arc glowing sparks inward to a synthetic beat, with geometric shape bursts on peaks. Click for a celebratory burst.
Current settings: intensity = 1, gravity = 1, corners = All four, shape bursts on, hue = 300, color = Single, second hue = 100.
Tags: Canvas 2D, fireworks, particles, click, pooled.
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.
