 * Covers the fixed top bar (#main-nav.nav-bar), the desktop link row
 * with its Services / Service Areas hover-and-focus dropdowns, and the
 * off-canvas mobile menu with its accordion sections. Color, radius,
 * spacing and timing values all come from custom properties defined
 * upstream; nothing in this file declares a custom property of its
