/* ==========================================================================
   CITIZEN CODE · feuille de style commune (v2)
   Même monde visuel que Citizen AI : blanc et gris #f5f5f7, encre #1d1d1f,
   typographie système (SF), un seul bleu d'action, violet de marque pour les repères,
   grandes tuiles arrondies sans bordure, beaucoup d'air. Thème clair unique, assumé.
   Mise en page d'un labo : couverture (titre, image, missions) puis mode mission
   (barre de mission, scène | code, le reste replié).
