/* ===================================================================
   POS System — visual layer
   Design notes:
   - Numbers are the content of this product, so every figure is set in
     tabular figures and aligned. That alignment is the signature, not decoration.
   - Ink sidebar / paper canvas: the panel reads like a ledger, the POS like a till.
