 10. ✅ Web source — `SourceType.WebSource`, pick list (all scenes), URI text input
 11. ✅ Elements scrollbar deselect fix — clicking the Elements panel scrollbar no longer deselects the selected element (scrollbar lives inside the ScrollViewer, not the StackPanel; guard now checks `ElementsScrollViewer` instead of `ElementsPanel`)
 12. ✅ Web source URI + buttons inline — merged URI TextBox and check/revert buttons into a single DockPanel row (✓ rightmost, ✕ left); buttons no longer wrap to a separate line
-13. ✅ Web source URI hidden for webcam (verified) — `SourceTypeToVisibilityConverter` returns Collapsed when `SelectedElement.Type` is null (WebcamSceneConfig has no `Type` property); URI section correctly hidden
+13. ✅ Web source URI hidden for webcam — URI section was showing for webcam due to WPF binding path `SelectedElement.Type` not resolving on `WebcamSceneConfig`; replaced with `IsWebSource` virtual property on `SceneElement` (mirrors existing `IsWebcam` pattern), overridden in `Source` to return `Type == SourceType.WebSource`, bound via `BoolToVis`
