/*
 * Site Header + Full-Screen Overlay Mega-Menu
 *
 * Architecture:
 *   - <header> is sticky (z-index 1020) with solid background.
 *   - Overlay panels are children of <body>, NOT of <header>.
 *     This puts them in the root stacking context where header (1020) > overlay (1015).
 *   - Nav items stretch to fill the full header height via align-items:stretch
 *     at every flex level. The selected item's dark background (var(--sspf-dark-surface)) therefore
 *     covers the full header height, connecting seamlessly with the overlay below.
 *   - The overlay uses top:var(--header-height) so it starts just below the header.
 *     The header paints on top of it (higher z-index), leaving only the area below
 *     the header visible, with the selected nav item's dark background as the bridge.
