{# The payment reminder dialog.

   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_stsa.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.
