 Der Editor erzeugt die vollständigen Move-Zuweisungen aus dem geladenen Tree,
 vergibt für neue Ziele vor dem Kommando eine stabile UUID und führt das
 Toolbar-Undo/Redo über die projektweite Historie aus.
+Die Projektgerätepalette belegt keine permanente Layoutspalte mehr. Sie wird
+über die Editor-Toolbar als überlagernder Drawer geöffnet, während das
+Stromkreis-Grid standardmäßig die gesamte verfügbare Breite nutzt. Auswahl,
+Schnelleinfügen und die vorhandenen Drag-and-drop-Payloads bleiben im Drawer
+unverändert verfügbar; während eines aktiven Projektgeräte-Drags kann er nicht
+geschlossen werden.
 `circuit.reorder-section` speichert die erwartete und neue Sortierposition
 jedes Stromkreises eines vollständigen Abschnitts. Forward, Undo und Redo
 ändern ausschließlich `sortOrder`; Stromkreisblöcke, Gerätezeilen und BMKs
