/*
 * The public site's stylesheet.
 *
 * Deliberately a copy of the product's tokens rather than an import of them. This site is
 * deployed as its own Static Web App from plain files with no build step, so it cannot reach
 * into `apps/web`; and the two have different jobs, so a shared stylesheet would couple a
 * public page to the app's layout every time a screen changed. What must stay in step is the
 * palette, the two typefaces and the shape of a button, which are copied below and are the
 * whole of the brand.
 *
 * Source: `apps/web/app/globals.css`. The landing layout follows the prototype's own landing
 * page — `Docs/kindred_courier_prototype_final/screens/landing_page` — hero text beside a soft
 * blob, then a three-feature strip.
