/* The public clinic verification gate.
   A card over the site for visitors who have not signed in yet. The prototype is
   docs/design/prototypes/kaltera-portal/index.html, view #gate.

   Every class here starts with kgate, and the tokens live on .kgate, so the site's own
   variables and its existing .gate block classes are untouched. */
