The list-selected draggable layer is temporarily raised in preview z-order and custom hit-testing; deselection restores the scene's unchanged order (`SelectedLayerPreviewHitTestingTests`). **TASK 57:** dragging/resizing a webcam in the vertical tier routes through `MainViewModel.MoveWebcamInVerticalTier` / `ResizeWebcamInVerticalTier` for the six-spot snap or Chat camera's two sizes. |

Source add/edit/remove, list drag-to-reorder, snapshot revert-accept. **TASK 51:** the webcam properties carry the Background section — `RemoveBackgroundPill` / `BlurBackgroundPill` (`PillToggle`, radio-exclusive via `WebcamSceneConfig.RemoveBackground`/`BlurBackground`) + `BackgroundStrengthSlider` (0..1, 5% snaps, shown only while an effect is on). **TASK 57:** the webcam properties carry a Geometry section (X/Y/W/H) — manual placement of the camera, bound to the **live** placement (the one the current tier shows), gated on `IsWebcamSelected` (not `SelectedElement.IsWebcam` — the TASK 51 test finds that panel by binding text and would match twice); the Shape button's `Visibility` is bound to `CanToggleClipShape`, so the circle option is NOT OFFERED in the vertical Chat layout. **TASK 58:** every drop-down, check box and field in the properties panel carries the theme's style (`YtComboBox`/`YtCheckBox`/`YtTextBoxCompact`) and paints no colour of its own — the guard is `ytLive.Tests/PropertiesStyleTests.cs`. **TASK 59:** the webcam's properties are a HIERARCHY — a `Shape` title owns the mirror switch and the shape choice (`Rect` | `Circle` as two `SegmentToggle` options, Rect selected by default, the circle option hidden where `CanToggleClipShape` is false), and every titled block (Geometry, Border Color, Border Thickness, Background) owns its content one indent deeper (Strength sits under Blur). **TASK 60:** the border-colour drop-down builds its menu from `Models/BorderColorPalette.cs` — each row is the hex plus the colour's NAME (`#e94560  Crimson`, tooltip "Crimson (#e94560)"); the swatch icon is unchanged. **TASK 61:** the four geometry fields (X/Y/W/H) share one fixed width (44px — the largest value, 1920, plus a sign) and their rows set `LastChildFill="False"`, so Y/H no longer stretch to fill the row. **TASK 62:** the border-colour field shows the palette's name beside the hex (`SelectedElement.BorderColorName`, empty for a custom hex) and keeps a fixed width so the name stays next to the hex. **TASK 63:** the border colour is picked with the **app's own drop-down** (`YtComboBox`) — the `...` button and its code-built `ContextMenu` are gone; the closed box shows the swatch + the colour's NAME, the rows show swatch + hex + name (the panel's own `DataTemplate`s + `Helpers/ClosedBoxTemplateSelector.cs`), and the hex field stays for a custom colour; `IsDescendantOf` falls back to `LogicalTreeHelper.GetParent` / `TemplatedParent` when `VisualTreeHelper.GetParent` returns `null` (at `PopupRoot`) so clicking a popup row does not trigger `MainWindow`'s deselection guard |

The layer owns all chat behavior — `Messages` buffer, `ChatBoxRenderer`, fade timer, mock-preview timer, per-source preview renders, live-output `RenderFrame`. The VM keeps only the binding surface: `ChatMessages` (delegates to `_chatLayer.Messages`, so XAML bind + LeftPanel `CollectionChanged` hold), `CanAddYouTubeChat`/`ShowChatInactiveMessage` (computed + `OnPropertyChanged` from VM setters), and thin forwards. Scenes are handed in as args (no `Func` seam) so the layer stays scene-graph-free. Zero behavior change; 246 pass / 2 known.

The resolution picker and live readouts (bitrate/FPS/dropped/duration) are in the top-left cell above the layers panel; the bottom bar is an empty height-preserving spacer.
