/* =============================================================================
   MOURN — NAVBAR (global component, single source of truth)
   Mobile-first. Desktop bar and mobile hamburger pattern share one markup
   tree (resources/views/components/navbar.php); this stylesheet switches
   presentation at the desktop breakpoint rather than duplicating markup.
   Desktop breakpoint: 1024px — below it (mobile + tablet) gets the
   intentionally-designed mobile pattern, not a shrunk desktop bar.
