   Shared by every page that carries it (the landing page, the sign-in page and
   the previews), so these rules exist in one place rather than per page.
   The drawing itself is js/welcome-next-bg.js.

   --wn-net lives here rather than on a body class because the script reads it
   from the ROOT element. The name is unique to that script, so nothing else can
   pick it up by accident.
