<%# Markup for the confirm-bridge demo.
    The controller intercepts the danger button (request action), shows the accessible
    alert dialog with the message, and only continues the form submit when confirmed.
    The dialog reuses the shared FocusTrap (trap, restore, Escape=cancel). This
    Playground has no backend, so demo.js cancels the real submit and reports the
    outcome from the resolve event. %>
