 ### Ankündigungen/Tickets
 - Farbmarkierung in Ankündigungen sauber an Rundungen/Containergrenzen angepasst.
 - Read-All-Aktionen mit Tooltip versehen und auf dezenten Hover-Hintergrund im Navbar-Stil umgestellt.
+- Empty-State-Kacheln ("Keine Ankündigungen"/"Keine Tickets") in Höhe und Gewichtung vergrößert.
 
 ### Dialog "Konfiguration anzeigen"
 - Optisch an Haupt-GUI angeglichen und vergrößert, um abgeschnittene Inhalte zu vermeiden.

 - Alt+F4 minimiert in den Tray statt vollständigem Schließen.
 - `isDraggable` aus Web-Konfiguration wird korrekt berücksichtigt.
 - Mehrdeutigkeitsfehler (`Brushes`) behoben.
+- Vor erfolgreichem Konfig-Ladevorgang wird die Oberfläche analog Offline-Zustand eingeschränkt (nur Info-Navigation und Info-Panel sichtbar).
+- Header-Verbindungsindikator für Offline/Verbindungsaufbau im Top-Bereich neu positioniert, damit er nicht von Action-Buttons überdeckt wird.
 
 ### Lokalisierung
 - DE/EN-Ressourcen sprachlich bereinigt und vereinheitlicht.
