   OnePoint POS — single stylesheet for POS + Admin
   Design language: quiet paper-and-ink minimalism. One signature
   element — the order panel is a live receipt: monospace tabular
   numerals, dashed rules, a perforated tear-off edge. Everything
   else stays disciplined: hairlines, generous tap targets, one accent.
