Build a multi-column footer with Tailwind CSS: a brand block on the left (logo, one-line description, social icons) and four link columns on the right, each with a small uppercase heading and five or six links. Add a bottom row separated by a hairline with the copyright, legal links and a language selector. Keep link text small and muted, headings at text-xs uppercase, and let the columns collapse into two-by-two on mobile.
