/* Lightbox v2 — gallery images in the core Popup <dialog>
   See core/assets/js/lightbox.js and core/templates/components/lightbox.php

   Full-screen, dark, image first: counter top left, toolbar top right beside
   Popup's own close button, arrows at the screen edges, thumbnail strip along
   the bottom. v1 is "lightbox - v1 (simple).css".

   ⚠ Loaded AFTER popup.css (page CSS follows the layout's static popup tag),
   which is what lets these rules win at equal specificity.
