/* ===================================================================
   DESIGN TOKENS
   Palette grounded in the Market itself rather than a generic SaaS
   look: deep pine green (produce, market signage) as the primary
   action color, warm mustard as the "notice me" accent (frequently
   ordered, in-progress), warm brick-red reserved only for errors.
   System font stack: fast, reliable on store wifi, no external
   dependency that could fail to load on a shared tablet.
