/// <para>The pattern is the one that <c>UnitTest1.MainPage_Should_Load</c>
/// established: a test attribute <c>[AvaloniaFact]</c> (from
/// <c>Avalonia.Headless.XUnit</c>) instead of plain <c>[Fact]</c>,
/// <c>new MainWindow()</c>, <c>window.Show()</c>. The AvaloniaFact
/// attribute schedules the test body inside a dispatcher, which
/// is the precondition for the headless Window's
/// <c>PlatformManager.CreateWindow()</c> to find a registered
/// service. A plain <c>[Fact]</c> test that calls
/// <c>new Window().Show()</c> throws because the harness has not
/// been initialised for that thread.</para>
///
/// <para>The session banner's <c>DataContext</c> is not wired in
/// these tests: <c>App.OnFrameworkInitializationCompleted</c> is
/// not called in a unit test, so we set the DataContext on the
/// banner directly. The production code path is exercised
/// end-to-end by the manual launch, not here.</para>
