/* ============================================================================
   DOCUMENT CARD (.doc list + .dc card) — shared single source of truth.
   EXTRACTED from comp-doc-card.html (Jun 2026, the _cover.css precedent) so the
   catalogue card is one file for the DS preview card AND the prototype's
   catalogue "Karty" view. Behaviour (wrap-aware meta fitter + render builder)
   lives in _doc-card.js.

   Consumes the shared chip components (_chips.css) and buttons (_buttons.css)
   — link those first. Dark is a co-located token revalue (notes/architecture).
   The chip-hover overrides beat the chip base by SPECIFICITY within the shared
   @layer components (`.dc:is(:hover,…) .vchip.v-valid` (0,4,0) > `.v-valid`).
