   1. Design tokens (couleurs, typographies, espacements)
   2. Réglages de base & accessibilité
   3. Mise en page (header, footer, conteneurs)
   4. Composants (boutons, cartes, badges, stepper, stats, formulaires)

   l'environnement et la confiance institutionnelle ; l'orange terre cuite
   (argile latéritique, très présente sur les sols camerounais) apporte la
   chaleur humaine et signale les actions prioritaires (dons, adhésion) ;
   le sarcelle évoque la matière PET recyclée travaillée par l'association.
