/* ============================================================
   app.css — "Terminal Noir / Operator Grid"
   Dichte, dark-first Operator-Konsole. Farbe = Zustand (knappes Budget),
   90% der Flaeche ist neutral-grau. Tiefe = 1px-Hairlines, keine Schatten.
   Mono (tabular-nums) fuer alle Zahlen/IDs/Status/Timestamps/Logs.

   White-Label: layout.html injiziert die Tenant-Farbe NUR in --accent
   (Links/aktive Nav/Selektion/Fokus). Flaechen + Statusfarben bleiben fix.
