/* ============================================================
   The front door: sign in, sign up, invitations, resets.

   Wide screens: the story on the left (headline, the app itself,
   what is inside, how it works) and the form held in view on the
   right. Phones: a hero with the real app on two phones, the form
   as a card rising out of it, then swipeable feature cards. Pages
   reached from a link (invitation, reset, confirmation) put the
   form first on a phone: the visitor already has a job to do.
   The app's own palette, so stepping inside feels like one product.
