   KI für meinen Betrieb – Stylesheet
   -------------------------------------------------------------------------
   Aufbau:
   1. Schriften (lokal eingebunden, keine Verbindung zu Google)
   2. Design-Variablen (Farben, Abstände) – hier zentral anpassen
   3. Grundlagen
   4. Layout-Bausteine (Container, Sektionen, Buttons, Karten)
   5. Einzelne Bereiche (Header, Hero, Probleme, Bots, Demo, Ablauf, ...)
   6. Demo-Geräte (Chatfenster, Handy)
   7. Animationen & Hilfsklassen
   Mobile first: Grundstile gelten fürs Handy, größere Bildschirme per
   @media (min-width: ...).
