/* Tracks — marketing + legal site.
 *
 * Tokens are lifted from tracks/constants/theme.ts so this page and the app are
 * recognisably the same product. Dark is the app's native mode; light is the
 * alternate, exactly as in the app. No build step, no framework, no fonts
 * loaded over the network — the rounded face is the system one on Apple
 * devices and degrades to the platform UI font elsewhere.
