   COMPONENT: HERO
   VERSION: 0.2
   STATUS: freigegebene Entwurfsrichtung

   REFERENZ:
   Aufbau bewusst näher an gorbel.eu:
   - kompakter Hero statt 100vh-Bühne
   - Bild vollflächig
   - Textblock links
   - klare Vorzeile, Headline, Subline
   - genau zwei Aktionen
   - drei direkte Einstiege unmittelbar unter dem Hero

   SAS-DIMAG-UNTERSCHIED:
   - dunkler, technischer
   - höherer Kontrast
   - Veilchen nur als Akzent
   - Forschung/Elektronik statt Service-Charakter
