/* ---------- plate clusters with an auto-scrolling gallery ----------------
   Pure CSS — no JavaScript, so nothing to load and nothing the CSP can block.
   The track holds each plate twice; the animation slides it exactly half its
   width, so the loop is seamless. The duplicate set is aria-hidden and is
   dropped on touch screens and for reduced-motion users, who get an ordinary
   swipeable row instead.

   To add a company: add one entry to the cluster in _build/content_*.py.
   If a cluster grows past ~10 plates, raise --dur so it does not race past.  */
