   ----------------------------------------------------------------------------
   Chargée APRÈS les styles inline de chaque page (donc elle a le dernier mot).
   Additive uniquement : profondeur, dégradés, survols, focus, typographie.
   Ne touche à AUCUNE logique ni à aucune dimension structurante.
   S'appuie sur les tokens déjà définis dans chaque page (--ink, --accent…).
