/* ============================================================
   css/navbar.css
   
   FIXES:
   1. Breakpoint unified to 992px everywhere.
      - Previously: layout.css hid sidebar at ≤991.98px,
        navbar.css hid search/auth at ≤992px,
        and the hamburger button used Bootstrap's d-md-none
        (hidden above 768px) — leaving a 768px–991px dead zone
        where the hamburger was invisible but the sidebar was
        off-screen. Users on those screen widths had NO way to
        open the sidebar.
      - Fix: hamburger is now always visible at ≤992px via
        .navbar-container rule instead of relying on Bootstrap's
        d-md-none utility class. The d-md-none class is removed
        from the button in navbar.component.js (see that fix).
   2. Gradient now references --gradient-brand token instead of
      the hardcoded value repeated across 4+ files.
   3. :last-child selector replaced with explicit ID selector
      for the user menu — fragile DOM-order dependency removed.
