   ZeeApps — Authentication screens
   Sign in · Register · Forgot password

   A single centred card floating over a full-screen animated aurora. The card
   carries both the identity and the work; the background carries the mood. One
   layout for all three screens, so nothing shifts by a pixel as a user moves
   between them.

   Depends on zee-tokens.css and zee-ui.css.
