    "Std_CloseAllWindows": "React gathers Save/Discard/Cancel decisions, the native close helper saves real FCStd files, the adapter persists their bytes to OPFS, and a revision-checked native close clears the mounted view and selection while preserving the workspace.",
    "Std_DockViewMenu": "Native handler resolves mounted dock identities and visibility preferences; the mounted host applies returned actions to real sidebars.",
    "Std_TileWindows": "Native handler enumerates actual open FreeCAD documents and activates the selected document; the mounted host tiles WebViewTask instances that load native document meshes through the existing facade.",
    "Std_ToggleToolBarLock": "Native handler reads and toggles the toolbar lock preference; the mounted toolbar disables location changes while locked."

    "The Web host mounts one view per open document; additional native Qt MDI views are not mirrored into browser windows.",
