/* The MTB east site header as drawn on the pages that aren't Next.js pages (the Sofa to Singletrack app and the games
   hub) -- see games/site-nav.js, which builds the markup and is the only place the link list lives on this side.
   Matches the website's SiteHeader.tsx: 64px row, #111111, Oswald 14px links, #e6530f on hover and for the current
   page, the real logo, the filled-orange "Enter a race" and the teal-outlined "Sign in" / "My Account". Every control
   is at least 44px tall. The desktop row (links + dropdown groups) shows from 1280px, the website's xl breakpoint;
   below that it's logo + "Enter a race" + a hamburger whose panel lists every link under group headings, as the
   website's MobileNav does. Dropdowns and the menu are <details>, so they open and close without any script. */
