   SUPPORT WIDGET
   Loads on every marketing page, so it owns a narrow set of
   class names and inherits nothing from the page around it.

   The launcher arrives as a pill that says what it is, then
   folds itself down to a circle a few seconds later. A bare
   bubble makes people guess; a permanent pill sits on the
   content. This does the introduction and then gets out of
   the way.
