/*
 * OPD Simple download site. Colours, radii and fonts follow the app's own tokens (src/styles/tokens.css):
 * clinical teal on grey-green neutrals, amber for waiting, green for done, lavender for "in consultation",
 * and system fonts only, so the page loads nothing from other sites.
 * Layout: grey-green ground with white bands for the practical parts (download, steps, questions) and one
 * dark band for contact; the hero pairs the pitch with a queue and a prescription drawn like the app.
