   HandicapLab — Website
   Design-System „Range x Fairway Gruen". Dark ist der Leitmodus, Light die
   Ableitung. Fairway Gruen ist der einzige Signalton: Marke, Aktiv-Zustand,
   Verbesserung. Kein Systemblau, keine zweite Aktionsfarbe.

   Radien-Regel (eine, ueberall): Karten und Bento-Zellen 22px, Flaechen
   innerhalb einer Karte 14px, alles Interaktive voll gerundet (Pill).
   Geraeterahmen 44px aussen / 36px innen (aussen minus Polsterung).
