/**
 * Site header, nav, apps overlay, menu overlay.
 *
 * Reads EXCLUSIVELY from tokens.css so the header visually matches every
 * other component (cards, buttons, hero, etc). Structure:
 *   .mlt-header              sticky top bar
 *   .mlt-header__nav         inline links on desktop, hidden on mobile
 *   .mlt-hamburger           visible on mobile + desktop (opens menu)
 *   .mlt-overlay             shared overlay shell — used by apps + menu
 *   .apps-list               plain list inside apps overlay
 *   .menu-account-card       account card inside menu overlay
 *
 * Legacy class names kept as selectors in JS event wiring only (ids like
 * #hamburger-btn). Everything visual was renamed and rebuilt.
