/* ============================================================
   Gallery Stack — frontend CSS (v1.5.36+).
   Replaces the inline 2-col grid that lived in gallery-stack.php.

   Layout strategy:
     - Desktop (>=1025px): CSS-column masonry. 2 columns, free
       image heights, marketing uploads whatever sizes/aspects
       they like and the columns flow naturally.
     - Tablet (769-1024px): same masonry, tighter gap.
     - Mobile (<=768px): horizontal scroll-snap slider with arrow
       buttons + dot indicator. Same swipe pattern as the
       Routine Builder cards.

   Each image is a <button class="wlpp-story-grid-item"> so
   keyboard + screen-reader users can open the lightbox the same
   way mouse users do. The PhotoSwipe init is in gallery-stack.js.
