/*
  StoreHarmony — the TradeX landing pages (2026-10-20): TradeX for Suppliers
  (web/supply/) and the TradeX home page for producers (web/tradex/). One look
  for both: a dark hero with the product drawn in HTML, sections on white and
  soft grey, cards, a worked example, questions and a closing band.

  Loaded as /sh/app/shell/landing.css, written from the root because both
  pages also show at a bare web address. No outside fonts. Light and dark
  follow the device.
