   DESIGN DIRECTION

   The people using this are selling from a phone, often on mobile data, often
   standing in a shop. So: one column, large touch targets, and the primary
   action always reachable with a thumb. Desktop gets the same layout with more
   air rather than a different one — a second layout is a second thing to keep
   working.

   Ink teal carries structure and every primary action. Lime is the accent and
   appears roughly once per screen — on the progress bar, a success tick, the
   focused input. Used on every button it stops meaning anything.

   Type is one family at four sizes. A merchant onboarding does not need
   typographic variety; they need to know what to do next.
