/* The one header and menu of toolswithterry.com. Every page loads this file and
   assets/nav.js; the markup comes from terry_tutorials/make_guide.py (NAV_HTML,
   `python terry_tutorials/make_guide.py --sync-nav` writes it into the static pages).
   Self-contained on purpose: no page variable is needed, and every rule is scoped to
   .nav so a page's own a, ul, li or .brand rules cannot change it.
   Gate: tests/test_terry_guides.py (same links, same order, on every page). */
