/* ==========================================================================
   PASS — design system (styles.css)
   Mobile-first, clair / sombre, sans build. Inspiré de CardioR2C, identité
   propre : accent indigo, série = flamme orange, XP = ambre/or.

   SOMMAIRE
     1. Tokens (:root clair) + thème sombre
     2. Base (body, liens, focus, typographie)
     3. Shell historique (.wrap, .site-header, .rubric-row, .panel, .btn, …)
        — noms de classes conservés, couleurs passées sur les tokens
     4. Barre d'onglets (.tabbar — js/shell-tabbar.js)
     5. Couche composants .ui-*  (à utiliser pour les nouvelles pages)
     6. Mouvement (animations, prefers-reduced-motion)
     7. Compatibilité sombre des pages non migrées (couleurs codées en dur)
