   app.css — Gajeto loyalty demo

   Palette notes, because the brand red is a trap:
   #FF0000 is a pure primary. It is right for the logo and for large display
   numerals, and it vibrates unpleasantly at body size and fails contrast on
   white (4.0:1) for small text. So:
     --brand   #FF0000  logo, big numerals, thick rules only
     --action  #D40000  buttons, links, any red at text size (5.9:1 on white)
     --on-dark #FF3B30  red on the near-black chrome, where #D40000 is muddy
   Nothing loads from a CDN and no web font is fetched: the demo has to work
   from a folder, on a hotel wifi, in front of a client.
