/*
 * Design tokens — the only file allowed to contain a colour literal, a raw
 * font size or a :root block. tests/css-tokens.test.ts enforces that.
 *
 * This file is the canonical copy. `make sync-tokens` copies it to
 * api/app/static/css/tokens.css for the back office, and a test on each side
 * fails when the two differ. Edit here, never there.
 *
 * Breakpoints cannot be custom properties (media queries do not resolve var()),
 * so they are a convention the lint checks: 480, 768, 1024, 1280 — min-width,
 * mobile first.
