/*
 * Design system for the public Eilei marketing site (/about/*).
 *
 * Ported from the hand-authored HTML in `FertiTrack/about us/`, which is the
 * source of truth for this design. Two deliberate departures from a
 * copy-paste:
 *
 * 1. Every rule is scoped under `.eilei-site`. The clinical app is a
 *    Tailwind SPA sharing this document, so unscoped element selectors
 *    (`section{padding:88px 0}`, `a{text-decoration:none}`) would bleed
 *    straight into it.
 * 2. The tokens live on `.eilei-site`, not `:root`. ThemeContext writes
 *    `data-theme` onto <html> to recolor the clinical app; keeping these
 *    names off :root means switching theme can never restyle this site.
 *
 * Fonts come from the Google Fonts import in index.css rather than the
 * ~800KB of base64 @font-face blocks the source HTML inlines per page.
