   v6 — full rebuild.  Editorial dark "contact-sheet" with a principal
   hero plate and two counter-weights.  Refined gold hairline frame,
   corner brackets, slow film-grain ambient, and a thumb-friendly
   responsive collapse.  Keeps the existing class API so the JS that
   injects cards needs no changes.
