/* ============================================================
   AVENIS — Shaping Tomorrow.
   Design: warmes, helles Bone als Leitfarbe (freundlich, viel
   Licht), Salbei/Olive (aus dem Logo) als durchgängiger Marken-
   akzent, ein dunkles Graphit-Grün (statt reinem Schwarz) für
   Header, Footer und dunkle Abschnitte. Echte Landschaftsfotos
   in Hero und Seitenköpfen mit Verlaufs-Overlay in Markenfarbe.
