/*
 * POINTPAL guest app.
 *
 * One stylesheet, no framework, no build step — this deploys by copying files to a
 * Windows box, and introducing Node tooling for a stylesheet would be a bad trade.
 *
 * Design direction: the app is used standing at a counter with a cashier waiting. The
 * visual anchor is the scan ticket — a paper-receipt form with a perforated edge and a
 * hard black rule — and everything else stays quiet so it never competes with the thing
 * the guest actually opened the app to show. Merchant brand colour is injected per card
 * as --brand, so the app chrome is deliberately neutral: it has to sit next to fifty
 * different restaurant palettes without clashing with any of them.
 *
 * Typography is the system stack. That is a real decision, not a default: a web font is
 * a blocking download on a bad connection in a basement restaurant, and the one screen
 * that must never wait is the one with the barcode on it.
