Testimonial Globe
Testimonial cards orbit a glowing core on a virtual sphere. The globe spins on its own, and you can drag to spin it with momentum or click a card to bring it to the front. Depth drives each card's size, blur, and fade, with faint links wiring neighbors into a nexus.
Build a self-contained, performant Canvas 2D visual effect in a single React + TypeScript component.
Effect: "Testimonial Globe".
Description: Testimonial cards orbit a glowing core on a virtual sphere. The globe spins on its own, and you can drag to spin it with momentum or click a card to bring it to the front. Depth drives each card's size, blur, and fade, with faint links wiring neighbors into a nexus.
Current settings: cards = 7, spin speed = 12, spin direction = Forward, radius = 300, auto spin on, nexus links on, color = Dual, hue = 200, 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.
