Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Cursor Attractor".
Description: Particles emit from your cursor and are pulled toward (or pushed from) the center with additive glow trails. Click to burst.
Current settings: force = Attract, force strength = 1, emit rate = 2, trail length = 12.
Tags: Canvas 2D, particles, pointer-reactive, 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.
