/* SpareFlow Web - Oberflaeche im Stil des dunklen Admin-Panels
   (Vorlage: 01 Input/UI/design-modern-dashboard-web-application-admin-panel-ui.png)

   Dunkles Theme, feste linke Navigationsspalte mit Icons, obere Leiste mit
   Seitentitel + Benutzer-Chip, Karten/Kacheln mit weichen Kanten, ruhige
   Tabellen mit Hover. Alle bestehenden CSS-Klassen der Templates bleiben gueltig.
