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

   Layout strategy:
     - Desktop (>=769px): 2-column CSS grid. Tiles fill LEFT-TO-RIGHT
       in reading order (image 1 top-left, 2 top-right, 3 below-left,
       4 below-right) so the on-screen order matches the sequence set
       in the Story images box. Tiles keep their natural proportions
       (no crop) at a fixed column width, so portrait/landscape
       uploads show in full. (Was a uniform square crop at
       v1.8.13-1.8.14; before that a CSS-column masonry, which
       filled column-by-column and showed images out of reading
       order. The grid keeps reading order; dropping the square
       crop restores the original rectangular look.)
     - Tablet (769-1024px): same grid, tighter gap.
     - Mobile (<=768px): horizontal scroll-snap slider with arrow
       buttons + dot indicator. Same swipe pattern as the
       Routine Builder cards. Images keep their natural proportions
       here (one per view), so no square crop is applied.

   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.
