/* ==========================================================================
   Galeria zdjęć w artykułach bloga.

   Przeniesiona ze starego motywu bez zmian w działaniu: ta sama siatka,
   ikona lupy i lightbox z nawigacją (skrypt js/gallery.js). Nazwy klas
   gallery-* i lightbox-* są własne, więc nie zderzają się z Tailwindem.

   Plik jest statyczny — NIE przechodzi przez build Tailwinda.
