/* ============================================================
   QuickPOS — Design System
   Aesthetic: offline-first receipt-tape / field-industrial.
   Palette: ink navy, signal amber (the "offline" warmth),
   money emerald, warm paper. Data set in monospace.
   Deliberately avoids cream+serif+clay, black+acid, and
   broadsheet-hairline AI defaults.
