/* =========================================================
   DERICE — v13 « ATELIER CLAIR »
   Refonte — ATOM Studios

   Direction : version CLAIRE, ambiance plan d'atelier / fiche
   technique. Fonds RAL 7035 (#d7d7d7) et blanc cassé, texte
   charbon, photos en noir & blanc contrasté (filter CSS),
   filets d'un pixel partout, angles vifs (--radius: 0),
   trames de plan en fond de hero.

   Identité : RAL 7035 reste la couleur de marque. Sur fond
   clair le logo se pose en CHARBON ; là où il doit s'imposer
   (lockups des deux pôles) il passe en RAL 7035 dans un
   CARTOUCHE CHARBON — les deux traitements demandés au brief.

   Les variables --teal* sont conservées comme ALIAS (sélecteurs
   .text-teal, .tealtile… hérités de la base v11) : elles ne
   désignent plus du teal mais l'encre / le RAL.
