/* =========================================================
   GRAIN-HINWEIS
   Header/Footer tragen keinen eigenen Grain-Layer mehr.
   Die Fläche wird jetzt sauber über den globalen Body-Overlay getragen.
   Damit verschwinden die grauen Mobilflächen der alten Blend-Logik,
   ohne die matte Oberflächenwirkung komplett abzuschalten.
