/*
 * Gallery module — SD-39
 * Figma: content modules / Gallery (node 6361-114362)
 * Responsive image grid (2–4 cols) with two modes (lightbox / link),
 * client-side pagination (16/page) and an accessible <dialog> lightbox.
 * Module-level layout only — items use the gallery-item component, the close
 * control uses the close-button component.
