   5 distinct trajectories so the swarm never reads as a single

   and randomises duration (18-35s) + negative delay so phases
   are scrambled across the swarm.

   prefers-reduced-motion: handled in JS (animation simply not
   assigned). On (pointer: coarse) particles use the legacy
   floatSlow keyframe with longer duration to spare CPU.
