/* NollAI — Unternehmensseite.
   Eigenes Theme nach der Logo-Vorlage (15.08.2026): Dunkelnavy-Grund,
   Silber-Typo, Blau-Verlauf-Akzente, dezente Glows. Bewusst ohne externe
   Fonts und ohne JavaScript: schnell, datensparsam, wartungsarm — dasselbe
   Prinzip wie hallomut.de, aber eine eigene visuelle Identität (die drei
   Marken duerfen nie wie eine Seite aussehen). */
