A canvas particle comet that reads pointer velocity, not just position: a tight ember when you drift, a long azure-to-cyan plume with coral sparks when you flick. Idle, the particles coil into an ambient orbit ring. Fixed particle pool, pre-rendered sprites with additive blending, DPR capped at 2x, one rAF loop, offscreen-paused, static orbit frame under reduced motion.
