/*
 * Site header — Figma "Website" file, node 4194:549 (homepage desktop 1440) and
 * 4267:967 (homepage mobile 393); 4482:1919 / 4484:4325 for the light variant
 * the supporting pages use.
 *
 * On the homepage the bar is transparent and sits over the hero photo; a dark
 * scrim fades down from the top edge so the wordmark and links stay legible on
 * any photo. The supporting pages (/faqs, /validation, /privacy-notice,
 * /terms-of-service) add `.site-header--light` for the solid white bar in
 * Figma 4482:1919 — see the variant block below. This file owns the header on
 * every page; css/navigation.css is gone.
 *
 * Units: rem, like the rest of the site (1rem = 1px at the design widths, see
 * the <style> block in index.html). Breakpoint 992px matches the site's
 * "medium" collapse: below it the links move into a right-hand drawer.
 *
 * Fonts: Inter throughout, as in Figma — the bar has no display type. The
 * shared .button-pill sets Inter itself so it travels with the component.
