   Palette: deep indigo surface + electric teal accent (retail-tech, not
   generic SaaS blue), amber reserved ONLY for the offline/emergency state
   so it reads as a real signal, not decoration.
   Type: Sora (display / totals) + Inter (UI/body) + JetBrains Mono (prices,
   barcodes, receipt numbers — anything that must be scanned at a glance).
