/**
 * fc-nav.css - Amazon-style Navigation for All Roles
 *
 * Navigation redesign that replaces the sidebar+header layout with:
 *   Desktop: Two-row top nav (primary bar + role-specific tabs)
 *   Mobile:  Bottom tab bar (retail only) + full-screen menu overlay
 *
 * Gated behind body.layout-topnav for all roles.
 * body.layout-retailer-v2 adds retail-specific CSS (mobile bottom tabs, cart).
 * Uses CSS custom properties from style.css for theme support.
