/* ──────────────────────────────────────────────────────────────────────────
   Conscious UX Studio — shared component primitives
   Three card primitives + a unified tag/chip/star/tooltip system.

   Available primitives:
     .c-card-film   — 16:9 or 9:16 thumb, hover-plays, title overlay, clickable
     .c-card-essay  — image + headline + lede + cta, click-through (editorial)
     .c-card-meta   — icon + label + small body, no thumb (lab tiles, contacts)

     .c-stars       — star rating (5-star, supports fractional fill)
     .c-tag         — pill tag, with .c-tag--genre / --mood / --ai / --coll
     .c-chip        — slimmer chip (active filter, byline, status badge)
     .c-tooltip     — instant CSS tooltip on data-tip="..." host

   Naming uses `c-` prefix so existing classes (.card, .tag, .featured-card, etc.)
   continue to work and these can be adopted gradually.
