/* Galerie — disposition agnostique du thème (cartes, badges, boutons, recherche).
   Les tokens de thème (--g-*) ne vivent PLUS ici : depuis v1.3.22 ils sont
   compilés dans les bundles bootstrap par-mode depuis custom.scss, que Quarto
   charge deux fois (flatly = clair, darkly = sombre). Le vrai mécanisme de
   bascule de Quarto (échange de bundles + body.quarto-dark/.quarto-light)
   sélectionne alors les tokens via les règles :root de chaque bundle.
   NE PAS réintroduire ici de [data-bs-theme="…"] ni de @media (prefers-color-
   scheme: …) pour ces tokens : Quarto 1.10.18 n'émet jamais l'attribut
   data-bs-theme et un media query brut découplerait les cartes (toujours
   sombres en OS sombre, même sur page claire) — régression corrigée en v1.3.22. */
