/*
 * Gaadiwala — application stylesheet.
 *
 * The brief is a working instrument, not a marketing site: an office clerk
 * enters lorry receipts in it all day, and a proprietor reads it to find out who
 * owes money. So it is built to look like well-printed freight paperwork —
 * ruled tables, figures that line up in their columns, field captions in a
 * condensed face, and colour used to mean something rather than to decorate.
 *
 * The one deliberate flourish is the number plate: commercial vehicles in India
 * carry black-on-yellow plates, so a registration number is rendered as one
 * wherever it appears. It is the single most scannable thing in a list of
 * trips, and it comes from the subject rather than from a palette.
 *
 * Typefaces are system faces only — CLAUDE.md §3 rule 2 rules out a webfont CDN.
 * Bahnschrift (Windows) and Avenir Next Condensed (macOS) give the condensed
 * grotesque of a route board; everything falls back to a normal grotesque.
