/*
 * Event photo galleries — grid + lightbox.

 * Loaded only on pages that actually contain a baltimore-station/gallery block
 * (enqueued from the render_block filter in inc/galleries.php).
 *
 * Accessibility notes: tiles are real <button>s, so focus rings matter — the
 * outline is drawn outside the tile so it stays visible against a photo. Hit
 * targets stay >=44px because the grid never goes below 2 columns.
