/* ============================================================
   PHOTO GALLERY — shared pattern
   Basic responsive photo grid used by every simple photo-gallery
   page (workshop, illustration series, etc). Copy an existing
   gallery page (e.g. projects/ux-workshop-gallery.html) as the template —
   this file needs no changes to add a new gallery page.
   Swap .gallery-tile-img--placeholder divs for real
   <img class="gallery-tile-img"> tags as photos land.
