/* ---------- garment scene: needle bob + reactive skip/pucker ----------
   Ambient: all five needles bob in sync (multi-head machines are

   the root svg's data-event, set by drawDetection/fadeOverlay — no
   per-scene JS. Keyframe 0%/100% is a mid-stroke rest pose (not fully
   retracted) so prefers-reduced-motion still reads as "mid-operation". */
