    <!--
        Settings drawer — slides in from the right over the participants
        table when the operator clicks the rail's settings icon. Esc dismiss.
        Hosted inline (not as a separate Window) so the drawer feels like
        part of the main surface rather than a satellite. Width fixed at
        400px to give every setting a 320px input field after padding.

        The five tabs mirror the WPF host's settings groups so the operator
        finds the same toggles in the same places. The Appearance tab is
        new — tri-state Theme picker (System / Dark / Light) plus a peek at
        the accent palette so the operator can verify Wild Dragon brand is
        respected on a light desk.
