/* Kaser web — hand-written CSS. Brand teal mirrored from apps/mobile/constants/theme.ts.
   Visual system: a deep-teal "price board" band (header + page heroes, echoing the exchange-rate
   boards Syrians read daily) over a light body, and notched price-tag chips for every per-unit
   price — the cheapest store gets the solid green tag. All decoration is CSS-only: no images,
   no extra fonts, so the payload stays friendly to poor connections. */
