/* ═══ THE PLATE SCRUB ═══════════════════════════════════════════════
   The card is an archive drawer, not a two-state toggle. Moving across
   it walks every plate the piece has; each one is brushed in from the
   direction of travel (clip-path, the archaeologist's brush), the stack
   counter-drifts a few px inside its frame (looking into a vitrine),
   and one ember hairline — light, never a surface — draws along the
   caption to land on the price.

   Everything below is inert until public/js/site.js adds .is-live, so
   no-JS keeps premium.css's hem peel on .card__alt untouched. Only
   transform / opacity / clip-path animate: no layout is ever read back
   during a scrub, nothing reflows, and the grid stays composited.     */
