    // (Controls/PdfViewer.xaml).

    // Same trick as the ViewerState forwarding: the names stay, the storage moves. Every
    // existing call site - DocPaneBorder.CornerRadius in Tabs.cs, DocPaneShadow.Visibility in
    // FullScreen.cs, PagePreviewPanel and MarqueeLayer across the render and annotation code -
    // compiles untouched.
    //
    // Get-only is correct here: callers mutate the ELEMENT (its margin, radius, visibility), never
    // rebind the reference.
    //
    // NOTE the one thing that could NOT be forwarded: the card's MARGIN. It lives on the control
    // now, not on PaneBorder, because the control is what the layout positions. ApplySidebarSide
    // and ApplyFullScreen set ActiveViewer.Margin directly.
