   Documail — site vitrine
   Identité visuelle « Documail » : bleu marine + bleu ciel, accent vert
   doux, typographie Inter. Feuille autonome (le marketing tourne sur un
   service séparé, sans partager les assets du portail client).

   Police : Inter est demandée par la DA. La CSP du service interdit les
   polices externes (font-src 'self' data:) ; on déclare donc Inter en
   tête de pile et on retombe proprement sur la police système moderne
   (SF Pro / Segoe UI / Roboto) pour les postes qui n'ont pas Inter.
