  --signal   #0B7A57  Service-Layer-Grün des Graphen (#10B981, gemessen #0CB484),
                      auf L 26 % abgedunkelt, damit Text auf Weiß 5,3:1 erreicht.
  --signal-l #46C595  dasselbe Grün aufgehellt für die dunkle Betriebsfläche,
                      Sättigung bewusst unter 60 % (kein Neon).
  --guard    #E0820B  Config/Infra-Layer des Graphen (#F59E0B), dort liegen die Guards.
                      Farbton um 4 Grad Richtung Orange verschoben, damit es nicht als Gold liest.
                      Nur Status "gestoppt", nie Fläche, nie Button.
  --surface  #12201B  Tinte des Graphen: Service-Grün auf L 10 % abgesenkt, Graphit mit Grünstich.
  --ground   #FFFFFF  reines Weiß; --ground-2 #EEF2F0 kühles Grau, leicht zur Fläche gefärbt.
  --ink      #0F1A16  fast Schwarz Richtung Fläche; --ink-2 #52605A Nebentinte gleicher Färbung.
