   RhekTec – Design Tokens (v3, heller Look)
   Weiß als Basis, Anthrazit und Teal als Akzentfarben – nicht umgekehrt.
   Signatur: versetzte, farbige Rechteck-"Objekte" hinter echten Fotos
   (Hero, Julian-Portrait) statt Dashboard-Chrome oder Stock-Ikonografie.
   Bento-Grid für die Leistungen, damit echte Bilder unterschiedlich viel
   Raum bekommen statt gleichförmiger Kartenreihen.
