       DESIGN TOKENS (refonte 3.0)
       Une seule source de vérité pour les couleurs, la typographie et
       les rayons. Les anciens noms (--bg-dark, --bg-card, --text-muted…)
       sont conservés comme alias pour que tout le CSS existant continue
       de fonctionner ; les nouveaux composants (css/design.css) utilisent
       les tokens courts (--bg, --surface, --text-2…). Le thème clair
       redéfinit les mêmes tokens dans css/ui.css.
