/* ============================================================
   HOMAHANDSS — Collage Hero  (4 equal vertical video strips)
   ============================================================
   Four full-height columns, each an autoplay/muted/looped video —
   the real HOMAHANDSS hero footage from thecollectivesynergy.com —
   layered over a full-colour category-accurate still as the
   instant-paint fallback (these videos are cross-origin, so they
   won't decode in the sandbox preview, but play normally live).
   Text overlay cycles through editorial headline sets every 6 s.
   To swap imagery: update POSTERS / VIDEOS arrays below.
