/* Workouti site navigation - shared by every page.
   One source of truth: markup is identical on all pages, nav.js sets
   aria-current and owns every open/close behaviour. The index hero variant
   is .site-nav.on-hero (absolute over the hero, transparent). The sticky
   context bar (index, z-index 800) appears only after scroll, and this nav
   lives only at the top of the page at z-index 700, so they never fight. */
