/*
 * controleerbtwnummer.eu — front-end styling.
 *
 * Hand-written: no framework, no build step, no external requests. The
 * Montserrat typeface (400/700) is self-hosted under fonts/ (the reference
 * site loads the same face from the Google Fonts CDN; self-hosting keeps
 * the page free of external references), the banner images live under
 * files/ and the favicons under img/. The only runtime request a page
 * makes is the same-origin API call GET /api/validate/<vat>.json
 * (contract: docs/api-contract.md).
 *
 * The design mirrors the public site controleerbtwnummer.eu:
 *   - the translucent country-code strip over the EU-night banner;
 *   - the white hero title (with text-shadow) and the search form that
 *     floats over the banner (white input + blue search button);
 *   - the white CMS content block;
 *   - the light footer (navy text) with the outlined buttons and the
 *     navy copyright bar.
 * The breakpoints (1024 / 720 / 568 px) match the reference.
