/* ------------------------------------------------------------------
   Site-wide participant feedback widget.

   Everything is prefixed .ukn-fb- and every rule sets the properties it
   depends on, because this loads on top of Bootstrap 3 and a lot of
   older page CSS. Nothing here leaks outside the widget.

   z-index map: tab 1030, invite 1031 (below BS3 modal backdrop at 1040,
   so the tab cannot float over an open site modal); scrim 1055 and
   panel 1056 (above BS3 modals, and only ever open on user action).
