/* =============================================================================
   Révision DSCG — feuille de style unique (refonte du lot C).

   - Mobile d'abord (320 à 430 px), polices système, aucune dépendance.
   - Thème : automatique (prefers-color-scheme) ou choisi (<html data-theme>,
     écrit par PHP d'après le cookie du thème) ; jetons de couleur sur :root.
   - Une couleur d'accent par UE (classes ue-0 à ue-3, ordre du catalogue),
     palette validée pour le daltonisme ; toujours accompagnée d'un libellé.
   - Les états ne reposent jamais sur la seule couleur (✓ / ✗, textes).
   - Zones tactiles d'au moins 44 px ; aucun effet réservé au survol.
   - Transitions courtes, désactivées si prefers-reduced-motion.
