Frost Nova
A freeze blast that throws out tapered ice crystals, two expanding frost rings, and a cold central flash, then glittering frost drifts outward, settles, and snows back down. Auto-pulses at the center. Click to set off a fresh nova at your pointer.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Frost Nova".
Description: A freeze blast that throws out tapered ice crystals, two expanding frost rings, and a cold central flash, then glittering frost drifts outward, settles, and snows back down. Auto-pulses at the center. Click to set off a fresh nova at your pointer.
Current settings: ice shards = 18, blast power = 1, ring speed = 1, color = Dual, hue = 195, second hue = 215.

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.
