/**
 * Museum Gallery — Automuseums Brand
 *
 * Modern featured-mosaic gallery grid + lightbox for standard (non-FIVA)
 * museum pages. Mirrors the FIVA gallery layout, recolored to the
 * Automuseums brand system (blue) instead of FIVA green/gold.
 *
 * The gallery markup (template-parts/museum/gallery-section.php) uses the
 * shared .fiva-gallery-* class names. This stylesheet and the FIVA one are
 * never enqueued on the same page (FIVA vs non-FIVA templates are mutually
 * exclusive), so there is no selector conflict.
