   Tokens come from the Mini App (static/css/app.css, body[data-tg="light"/"dark"]): Inter, the accent
   #b68235 ramp, bg #f3f2f2 / text #201f1d / hint #605d5d. One change: the filled button uses a slightly
   darker accent (#93641d) than the app's #a06f24 so white text passes WCAG AA (5.2:1 instead of 4.4:1).
