   DEVENTRA — feuille de style unique
   --------------------------------------------------------------------------
   Direction reprise de l'identité en place : papier crème chaud, encre presque
   noire, un vermillon unique. Serif à fort contraste pour les titres, avec
   l'italique comme seul effet — il ne sert qu'à porter l'accent de la phrase.
   Le vermillon ne décore jamais : il marque un état, un accent ou une action.

   Type   Playfair Display (titres) · Inter (texte) · JetBrains Mono (données)

   Le motif structurant est la FICHE : un cadre à filet fin dont la légende
   coupe la bordure haute, comme une fiche technique. Il porte l'exemple du
   héros, les chantiers, les tarifs. C'est la signature visuelle du site.
