Bundle exception (2026-08-27): this lands prior-session work plus today's transparency fix as one commit per creator instruction. WebView2Manager (new): off-screen WebView2 control parked at -5000/-5000 in the window's visual tree, captures via CapturePreviewAsync every 100 ms into a BGRA8 VideoFrame. Source Width/Height sync to the control via PropertyChanged. JS transparent-background injection runs on every NavigationStarting/NavigationCompleted so the page's own CSS does not paint white over the capture. Transparency fix: DefaultBackgroundColor = System.Drawing.Color.Transparent set on the WPF control before EnsureCoreWebView2Async. The WPF SDK doc says the value is forwarded to the controller on init; the IDL (ICoreWebView2- Controller2) confirms alpha=0 makes the capture alpha-preserving. The prior-session 'CoreWebView2.BackgroundColor' path was the wrong property name and has been replaced. LayoutStore: WebUri column added (idempotent ALTER TABLE) and round-tripped on save/load (schema v11). MainViewModel: WebView2Manager constructed on Loaded; loaded web sources re-registered; Source.WebUri PropertyChanged forwards to manager. MainWindow: off-screen host Canvas added to visual tree. Tests: 3 scale-sync + WebView2_DefaultBackgroundColor_Is_Transparent + LayoutStorePersistenceTests.WebSource_WebUri_Persists. 234/236 pass (2 pre-existing failures unchanged). Scale bug (DPI/physical-pixel mismatch) still open.
