 * Design tokens reused from the live HDC site (ukhealthdata.org/health-data-connect/),
 * per SPECIFICATION.md's "Styling" section ("Reuse the existing styling developed
 * for HDC. Take it from their website and integrate.").
 *
 * Extracted by fetching the live page's two theme stylesheets:
 *   https://ukhealthdata.org/wp-content/themes/hdruk/assets/css/style.min.css
 *   https://ukhealthdata.org/wp-content/themes/hdruk-child/assets/css/style.min.css
 * and the site logo (public/images/hdc-logo.svg).
 *
 * NOT reused: the site's body font, Museo Sans Rounded, is a commercial
 * licensed font self-hosted under HDR UK's own license — copying those woff
 * files into this repo (or hotlinking their URLs) isn't something this spike
 * should do without checking licensing/hosting terms first. Quicksand
 * (Google Fonts, open license) is used as a similarly rounded stand-in;
 * swap for the real font once licensing is confirmed.
