   LOYALTY CARDS — the flows that have no shell
   ----------------------------------------------------------------------------
   Four kinds of screen live here, and none of them has a sidebar:

     auth        sign in, reset, the platform door
     onboarding  the questions that make an account into a business
     card        what a CUSTOMER sees when they open their card
     join        what a customer sees after scanning the poster

   The first two are our product and stay in the LoyaltyCards purple. The last
   two belong to the SHOP: they take that business's skin, which is why they
   are written against --brand and not against a hex.
