{# The reminder dialog for the groups that have not filled yet.

   A near-copy of core's `events/registration/management/email.html`, and it has
   to be a copy rather than a reuse: that template builds the preview URL with
   the relative endpoint `.email_registrants_preview`, which resolves against
   whichever blueprint is handling the request -- so rendering it from this
   plugin's blueprint asks Flask for
   `plugin_group_registration.email_registrants_preview` and raises
   `BuildError`.  The preview button keeps core's `preview-email` id, because
   core's own delegated click handler is what drives it.
