/* Mupay — feuille de style (v5)
   Concept : institution financière congolaise sérieuse. Fond clair dominant,
   une seule couleur de marque (bleu nuit) portée avec retenue, l'ambre réservé
   aux actions. De vraies photographies plutôt que des pictogrammes, des
   chiffres de confiance, une mise en page structurée comme une banque. */
