/* ============================================================
   GEROTECH — GALLERY MODULE (exploratory)
   Collection cards (multiple images + optional video per category)
   + a media viewer. Loaded ONLY by gallery-module-preview.html.

   Self-contained: namespaced `.gallery-collection*` / `.gallery-viewer*`
   so nothing collides with the legacy `.mcs-gallery-*` / `.gallery-lightbox`
   styles in components.css. Promote into components.css only if adopted.
