/* .nav__menu's real display:flex layout lives in the @media(min-width:769px)
   block further down (desktop-only, deliberately). A stray, unguarded
   ".nav--scrolled .nav__menu { display:flex; ... }" rule used to live here
   -- its properties were a strict subset of that guarded block, so it never
   added anything on desktop, but its higher specificity (two classes) beat
   responsive.css's single-class mobile-hide rule regardless of load order
   once #nav picked up "nav--scrolled" past 80px of scroll (main.js's
   separate "NAV SCROLL SHRINK" handler) -- silently bleeding the full
   desktop menu onto mobile after any scrolling. Same bug class as the
   .nav__inner !important issue documented below, just missed by the
   original fix since this rule's unusual multi-line/commented shape didn't
   match a simple grep for ".nav__menu". Removed rather than re-guarded,
   since the @media(min-width:769px) block already covers everything it did. */
