/* =========================================================
   Gallery CSS
   Romm Coffee — real cafe photos + short videos.

   Masonry-style columns mixing portrait/landscape stills and
   muted looping clips. Each item has an overlay caption; video
   items show a small badge and only play while on screen
   (see gallery.js). Teal brand throughout.

   Works with:
   - Pages/Gallery.cshtml
   - wwwroot/js/gallery.js
   - wwwroot/media/gallery/*.mp4  + wwwroot/images/gallery/*-poster.jpg
