/*
 * site.css — stylesheet for the static content pages.
 *
 * These pages (about, FAQ, guides, privacy, terms) do NOT go through the Expo
 * bundle: they are plain HTML inside `public/`, which the export copies verbatim
 * to the root of `dist/`. They are served without JavaScript so that any crawler
 * — AdSense's included — sees the full text in the first response, without
 * waiting for the SPA to hydrate.
 *
 * The palette mirrors `constants/colors.ts` by hand. If it changes there, change
 * it here too.
