   style.css – gemeinsames Stylesheet für alle Seiten
   Thema: Systemintegration – Industrie, Software und KI verbinden

   Gestaltungsidee: konservativ-modern. Ruhige Flächen, eine Akzentfarbe
   (Kobaltblau), klare Linien. Bewegung gibt es nur dort, wo sie erklärt,
   wie Daten fließen: im Leistungsschema, in den Datenwegen der typischen
   Fälle, in den simulierten Ergebnissen und im Projektablauf.

   Helles und dunkles Design über light-dark(). Ohne JavaScript folgt die
   Seite der Systemeinstellung; main.js ergänzt den Umschalter und startet
   Animationen erst, wenn ein Bereich sichtbar wird.
