/**
 * footer.css — Gradbau.com
 * Two-tier site footer + cookie banner.
 *
 * Top tier: 3 navigation columns (Услуги / Компания / Реквизиты)
 *           — structure from concept pages.
 * Bottom tier: copyright + privacy/cookies/cookie_settings links
 *              — links from production footer (kept via i18n keys
 *              footer_privacy, footer_cookies, footer_cookie_settings).
 *
 * Cookie banner (#cookie-banner) is included as-is from production —
 * it works through storage.js. Not refactored in this iteration.
