/* PhotoSwipe Custom Styling */

/* Fix: PhotoSwipe's .pswp__zoom-wrap has position:absolute with width/height:auto.
   With all-absolute children, the zoom-wrap gets 0 intrinsic width, causing
   the actual images inside it to have offsetWidth=0 and render invisible in
   Chrome/Edge.  Switching actual images (not placeholders) to position:relative
   puts them in normal flow, gives the zoom-wrap real dimensions, and makes them
   render correctly.  Placeholders are position:absolute inside .pswp__item and
   are unaffected by this rule. */
