/*
 * Mobile navigation overlay — applied site-wide.
 * Hamburger button + full-screen overlay shown at ≤980px (matches existing
 * desktop-nav hide breakpoints across all pages). Above 980px the desktop
 * nav remains and the mobile chrome is fully hidden.
 *
 * Colors hardcoded (no CSS vars) so this file works even when included on
 * pages whose inline <style> doesn't define :root brand tokens.
