/*
 * The Atom brand theme.
 * Atom is the default brand: the design system (design/system/tokens.css) is its theme, so there is nothing here.
 *
 * Another brand puts here only the tokens it overrides, and its fonts, for example:
 *
 *   @font-face { font-family: 'Brand Display'; src: url('./assets/fonts/display.woff2') format('woff2'); font-display: swap; }
 *   :root {
 *     --accent: #ff5a36;
 *     --on-accent: #111111;
 *     --font-display: 'Brand Display', system-ui, sans-serif;
 *   }
 *
 * Rules: only `var(--…)` from the system; no new classes and no !important. Contrast is checked
 * with axe in e2e for every brand (quality.md).
