    v5c: settings mode's own titlebar — SettingsNav.dc.html and the four Settings-*.dc.html sources all draw
    the same 53px bar: "Back to application" on the left, in place of the wordmark and the search box, and
    the same three window-control glyphs on the right TitleBar.axaml already draws.

    A separate control rather than a variant of TitleBar itself, on the same reasoning SessionStatusBar and
    SessionSidebar are their own files: nothing here can be measured by a test that hosts the real window,
    and a control that is either "the wordmark bar" or "the settings bar" depending on a bound flag would be
    two controls wearing one name. The dragging, maximising and closing logic is duplicated from TitleBar's
    own code-behind rather than shared through a base class — four short handlers, and the day one of the two
    bars needs its own window behaviour a shared base would have to be pulled apart first.

    v5c-3: two back buttons rather than one whose text and command a converter swaps, toggled by
    MainWindowViewModel.IsImporterOpen — Import.dc.html draws the same 53px bar with "Back to preferences" in
    place of "Back to application" while an importer is up, and CloseImportCommand closes it without leaving
    settings mode, unlike LeaveSettingsCommand.

    IsImporterOpen rather than IsImportOpen because there are two importers now — the ssh_config one and the
    Hetzner wizard — and this bar behaves identically for both: same label, same destination, same command.
