   Mobile (<=991px): tier-2 links move into the drawer; the four tasks stay.

   The layout is the one the site has always had. The modernising is in type,
   spacing, a single icon set, real hover/focus states and the outline-to-solid
   current-item swap — not in moving things around.

   Loaded from inc/header-nav.php, not inc/topscripts.php, so the CIPA-preserved
   topscripts.php needs no cache-buster bump. All rules namespaced .kn-*.
   Karns palette: blue #114a96, deep blue #0d3a75, red #ad1f34.
