/* =============================================================
   barrio_npm_prototype — image gallery grid + lightbox (shared component)

   Content-type-neutral. Any content type with field_image renders the grid
   via templates/content/_image-grid.html.twig (data from Media\GalleryBuilder)
   inside its own <section> + heading, and emits the shared #np-gallery-modal
   (_gallery-modal.html.twig + barrioNpmGalleryModal JS). The section wrapper +
   heading are owned per-content-type; the grid + items + lightbox live here.

   `data-count` on the grid keeps small-N layouts from stretching awkwardly:
     · 1 image  → full width + 16:9 poster (4:3 at phone)
     · 2 images → forced 2 columns
     · 3+ images → auto-fit grid
