+# Modul-Fenster
+
+Die Fenster der Module liegen bewusst **hier in der App** und nicht in den Modulprojekten.
+
+**Warum:** Die App ist der Kompositionswurzel – sie referenziert ohnehin alle vier Module. Damit
+bleiben die Modulprojekte (Trading-Engine, Scanner, Supervisor, Accounting) **frei von Avalonia**.
+Das ist für den kopflosen Linux-Betrieb (`--headless`) der entscheidende Punkt: der Daemon soll
+keine GUI-Bibliothek mitschleppen. Zusätzlich können die Fenster so die gemeinsamen Bausteine der
+Shell nutzen (`WindowMenuBar`, `SettingsEditor`, `DialogWindow`), ohne dass diese in eine eigene
+Bibliothek ausgelagert werden müssen.
+
+**Folge:** `IPolyTraderModule.RegisterUi` bleibt je Modul ein No-Op; registriert werden die Ansichten
+in `Shell/ModuleViews.cs`. Die stabilen View-IDs (`copytrading.main` usw.) bleiben unverändert,
+sodass Symbole, Reihenfolge und Launcher-Verhalten identisch sind.
+
+**Alternative, falls Module später doch ihre UI selbst mitbringen sollen:** eine gemeinsame
+Bibliothek `PolyTrader.Ui.Shared` mit den obigen Bausteinen anlegen und die Fenster in
+`PolyTrader.Modules.X.Ui`-Projekte verschieben. Der Aufbau der Fenster bliebe dabei unverändert.
