/* Postora — design system
   Identité propre (distincte de MyTransition) mais même philosophie graphique : variables
   CSS pour les couleurs, cartes, boutons, formulaires, badges, alertes, accessibilité
   (focus visible, contrastes, aucune information transmise par la seule couleur),
   responsive avec menu burger sur mobile. Palette "diffusion" : indigo profond + corail,
   qui évoque "publier vers plusieurs destinations" plutôt que le navy/or de MyTransition. */
