/* ==========================================================================
   SimVantage — site.css
   Ein einziges Stylesheet für die ganze Website.
   Design-Sprache: präzise und technisch. Helle, neutrale Flächen, feine
   Haarlinien, kleine Radien, dunkle "Simulations"-Bühnen (Navy) für Produkt
   und Physik. Inter (variabel, mit Display-Schnitt) für alles — Labels und
   Kennzahlen inklusive, mit Tabellenziffern statt Monospace.
   Aufbau:  1) Fonts  2) Tokens  3) Reset/Base  4) Layout  5) Header/Nav
            6) Hero   7) Komponenten  8) Homepage  9) Footer  10) Utilities
   Farben/Abstände/Schriftgrößen ändern? -> nur Abschnitt 2 (Tokens) anpassen.
