/* =============================================================
   Jundo Referenz-Bildergalerie – Bento-Layout-Grid mit Inline-Expand
   Mobile First | Breakpoints: sm 640px · lg 1025px

   Wird von js/referenz-layout-grid.js zur Laufzeit aus dem
   core/gallery-Block im Beitragsinhalt einer Einzel-Referenz gebaut
   (mind. 2 Bilder). Ohne JS bleibt die native Galerie sichtbar –
   dieses CSS blendet sie nur aus, sobald JS sie erfolgreich ersetzt hat.
