    Feature flags and optional functionality.

        use_authentication: Enable authentication for the app.
        show_session_picker: Show the session picker on the admin page. When
            False, sessions are still active in the runtime but the GUI hides
            the dropdown/new/copy controls — useful for single-tenant
            workshops where switching sessions would only confuse users.
