/*
 * Shared styling for the static content pages: /about, /help, /privacy.
 *
 * These three are plain files in public/ rather than React routes, for the
 * same reasons /i/index.html is: they must render for a reviewer with no
 * account, they must not depend on src/firebase/config.js resolving its
 * top-level await, and they carry their own <meta name="robots"> rather than
 * inheriting public/index.html's site-wide "noindex, nofollow".
 *
 * A shared stylesheet rather than the inlined CSS /i/ uses, because these are
 * long pages read once, not a label scan where a second request is a second
 * chance to fail. The visual language is deliberately identical to /i/ so a
 * customer who lands on both sees one product.
