// Burger Menu Component (menu ouvert)
// Two-column desktop layout: nav groups + portrait photo + contact block.
// Figma references:
// - Global overlay: node-id=92-109
// - Main links:     node-id=92-156
// - Secondary links: node-id=92-160
// - Contact block:  node-id=92-166
// Note: Burger toggle button (MENU / X) lives in _header.scss — the header
// stays fixed above this overlay (z-index) so it doubles as the menu's
// own top bar, matching the Figma frame.
