/*
 * Photo Grid Visualizer — self-contained styles
 *
 * Layout is driven entirely by CSS custom properties set inline by the renderer:
 *   --pg-gap      gap between images (default 8px)
 *   --pg-padding  horizontal inset from prose column (default 6%)
 *   --pg-cols     column count in uniform mode
 *   --pg-ratio    aspect-ratio for crop mode
 *   --row-cols    per-row column count in layout mode
 *
 * Two layout modes:
 *   .photo-grid             — uniform CSS grid, images auto-flow by --pg-cols
 *   .photo-grid--rows       — flex column of explicit-column row divs
 *
 * Lightbox: images are wrapped in <a class="pswp-gallery__item">, picked up
 * by PhotoSwipe when image_zoom is enabled in the theme (no extra config needed).
