   SimVantage — site.css
   Ein einziges Stylesheet für die ganze Website.
   Design-Sprache: an die SimVantage-App angelehnt — helle, blau getönte
   Flächen, weiße Karten mit großen Radien, weiche Schatten, Blau-Verläufe.
   Aufbau:  1) Fonts  2) Tokens  3) Reset/Base  4) Layout  5) Header/Nav
            6) Hero   7) Komponenten  8) Sections  9) Footer  10) Utilities
   Farben/Abstände/Schriftgrößen ändern? -> nur Abschnitt 2 (Tokens) anpassen.
