LeftPanel.xaml(.cs) takes the Row 1 Col 0 panel (layers + properties editor and
the live chat list). All property-editor/chat handlers moved into the control
(SourceNameBox edit, AddSourceButton menu, chat autoscroll self-subscribed on
Loaded, mirror/clip-shape, remove-source, background capture change/refresh,
opacity slider label, list drag-to-reorder, snapshot revert/accept family).
Window keeps only shell + routing: ctor wiring (_leftPanel), geometry, hotkeys,
taskbar overlay, BackToAbout, Window_PreviewMouseLeftButtonDown (uses
_leftPanel.IsClickInside), UpdateSelectionOverlay (calls _leftPanel.OnSelectionChanged).
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.

SceneThumbnailStrip.xaml(.cs) takes the Row 0 scene-picker strip (ItemsControl
over Scenes with staged/live border highlight); Thumbnail_MouseLeftButtonDown
moved into the control, transitioning via DataContext.TransitionToScene.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.

PreviewPane.xaml(.cs) takes the center preview (Row 1 Col 1): the 1920x1080
canvas (OverlayCanvas/SelectionOverlay/BrandFlashLayer/SocialBarElement),
the text pull-out drawer, and the live-controls row (TRAX / game / mic meters,
volume sliders, speaker toggles, socials button) inside the preserved
glow/background Border.
Code-behind moved into the control (drive by DataContext==MainViewModel):
preview drag/select/resize/hit-test (Preview_Mouse{Down,Move,Up},
EndPreviewDrag, HitHandle, HitElement), webcam context-menu handlers
(WebcamMenu_ChangeWebcam/SetBorderAnimation/StopBorderAnimation/
FindBorderShape/CreateBorderAnimation/AddDoubleAnimation/SetBorderColor/
HideInScene/Remove), social-bar glow (SocialBar_MouseLeftButtonDown,
SocialsButton_Mouse{Enter,Leave}, SocialGlowTick), audio controls
(VolumeSlider_*, GameVolumeSlider_*, MicSpeaker_*, GameSpeaker_*,
SetSliderValueFromClick, FindParent), and TraxButton_*.
Window keeps the left source/property/chat panel + thumbnail strip + overlay
host, and routes the selection overlay and preview hit-testing through the
control's public surface (_previewPane.UpdateSelectionOverlay(bool),
IsClickInsidePreview/Drawer, PreviewPane.IsDraggableElement). BackgroundMenu_*
stayed in the window because the left-panel source context menu uses them
(the preview's own desktop/refresh menu binds RefreshCaptureCommand instead).
Preserved the outer preview Border (background/glow/margin) that was initially
dropped in the cut — caught and restored before commit. Pruned now-unused usings
(System.Net.Http, Media.Effects, Media.Animation, Media.Imaging, Shapes,
Threading) from MainWindow.xaml.cs.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.

TopBar.xaml(.cs) takes the Row 0 top controls: logo/About button, REC/ON-AIR
pills + status signs, avatar, Sign In/Start/End buttons. The avatar fetch
(AvatarHttp/_loadedAvatarUrl/LoadAvatarImage/ShowAvatarFallback) moved into the
control with async semantics preserved; the window grabs the control via
FindName in its ctor and calls _topBar.RefreshAvatar() when IsConnected or
AccountAvatarUrl changes (previously OnViewModelPropertyChanged -> LoadAvatarImage).
AccountLight is pure binding (never touched by code-behind) so it moved with the XAML.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Also dropped the now-unused System.IO using from MainWindow.xaml.cs.

HealthBanner.xaml takes the Row 1 YouTube-health banner (report-by-exception).
Converters: promoted the 7 value<->visibility converters (BoolToVis, Inverse,
NotNull, Null, Hidden, EnumToBool, AllTrueToVis) from MainWindow.Window.Resources
into Themes/Controls.xaml so extracted UserControls can resolve them. AGENTS rule:
controls cannot reach into a window's own named resources; they resolve from the
app-level merged theme instead. Promoted all of them (not just NotNullToVis) so
every pending extraction keeps working without window-level references.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.

New Controls/ folder + namespace ytLive.Controls. BottomBar takes the
Grid.Row=3 footer: gear menu button (with its GearButton_Click handler moved to
the control's code-behind), centered stream-stats (bitrate/FPS/dropped/
duration/health), and the quality dropdown. All bindings inherit the window
DataContext; app-level styles resolve from Themes/Controls.xaml as before.
Zero behavior change; build 0 warnings; 246 pass, only the 2 known failures.
Docs: ViewModels/index.md tracker gains a Phase 2 section in the same commit.
