   Seven primary links cannot fit beside the wordmark on a 390px viewport. The
   header used to be a hard 60px with a wrapping .nav inside it, so the second
   row of links overflowed the header box. Two layers fix that:

   1. NO JS: the header becomes auto-height and the nav drops to its own full
      width row. Nothing is hidden — it just wraps somewhere it fits.
   2. WITH JS: app.js sets .js-nav on <html>, which collapses that row behind a
      Menu button. Progressive enhancement in this order matters — building the
      menu JS-first is exactly how primary navigation goes missing on mobile. */
