+===============================================================================
+nvWindow.py – Tkinter-Vorschlagsfenster für NV_MASTER-Abgleich (LibreOffice)
+===============================================================================
+
+Zweck:
+    Dieses Skript öffnet ein Tkinter-Fenster, das Live-Vorschläge zu Begriffen
+    aus der Datei NV_MASTER.ods anzeigt. Es ist so ausgelegt, dass es direkt
+    mit LibreOffice Calc über UNO kommunizieren kann – sofern möglich.
+
+Robustheit:
+    Das Skript erkennt automatisch, ob UNO verfügbar und kompatibel ist:
+      - wenn ja → direkte Integration mit LibreOffice (bidirektional)
+      - wenn nein → Fallback in isolierten Modus, aber weiterhin lauffähig
+    Alle Ereignisse, Fehler und Systemzustände werden geloggt.
+
+Start LibreOffice (empfohlen):
+    soffice --calc --accept="socket,host=localhost,port=2002;urp;" --nologo --norestore &
+
+Start der Anwendung:
+    /usr/lib/libreoffice/program/python3 ~/projects/nvWindow/nvWindow.py
+    (oder notfalls:) python3 ~/projects/nvWindow/nvWindow.py
+
+Abhängigkeiten:
+    pip install rapidfuzz odfpy
