+// RadialMenuWidget.h
+// Container for the radial menu, now a CommonUI activatable widget. It owns the
+// CommonUI input bindings (Confirm / Back) and routes them to the controller,
+// which still owns all state (time dilation, hover, Entries). The widget also
+// spawns one URadialSliceWidget per entry at runtime (variable slice count).
