/* =========================================================
   DERICE — v12 « ACIER & TEAL »
   Refonte — ATOM Studios

   Variante de la base v11 (sombre / acier). Le teal historique
   #21A6A5 revient comme ACCENT SECONDAIRE — il ne fait que
   ponctuer : boutons primaires, soulignés de nav, tags, eyebrows,
   filets, focus, coches. Le RAL 7035 (#D7D7D7) reste la couleur
   d'IDENTITÉ : logo, wordmark, grandes typos, grandes surfaces.

   Règle de partage, à tenir si le site évolue :
     --accent* (RAL 7035) = structure, identité, aplats larges
     --teal*   (#21A6A5)  = ponctuation, filets, éléments actifs
