/* =============================================================
   ZenithNord — the top navigation and the mobile menu
   Extracted from index.html 2026-08-27.

   It lived only in index's inline <style id="an-nav">, and the
   town pages happened to carry a copy in an-town.css. The three
   legal pages had neither, so when the nav markup was added to
   them it rendered as a raw bulleted list of links with every
   dropdown expanded. Shared here so a page cannot have the nav
   markup without the styling that makes it a nav.
