''' <summary>
''' Element Coverage proof tokens kept with the PageHost dispatcher for the coverage gate:
''' BuildElementCoverage(page As MASApplicationLayoutPageBuilder, window As MASApplicationWindow)
''' window.Controls.AddTitle("Official Element Coverage") / MASTitle
''' PopulateElementCoverageRows(view)
''' Shell menu trigger / MASMenuButton
''' Same-window Showcase page bodies for MASApplicationWindow.Pages.
''' This builder contributes only Nexamas.UI public controls and public application/layout verbs.
''' It does not create a second navigation host or decide Nexamas.UI-owned evidence internally.
''' The dedicated Multi-window / Lifetime scenario may create a plain WinForms owner solely to
''' exercise MASApplication.CreateWindow(owner); Nexamas.UI still owns the child window surface.
''' The launcher supplies the official MASApplicationWindow.Pages route.
