   Mode sombre — Flatboard utilise [data-theme="dark"] sur <html>
   ⚠️  On n'utilise PAS @media (prefers-color-scheme: dark) : Flatboard gère
       son propre toggle indépendamment des préférences OS.
       Les variables --bg-primary, --text-primary, etc. sont automatiquement
       remappées par le thème en mode sombre ; la plupart des surcharges
       ci-dessous sont donc redondantes mais garantissent la compatibilité
       avec les thèmes personnalisés qui n'utiliseraient pas les variables.
