/* ===== Shared hamburger menu (.nav-burger) =====
   The whole site nav collapsed into one hamburger at every width, with
   class-switcher.js's class panel and nav-teacher-menu.js's "As Student"
   rows merged in as one list (nav-menu.js). Extracted from Discover
   (journeys.css, "1a" mockup) so Discover and Levels share one copy —
   opt in with <body class="nav-burger"> + nav-menu.js. Page placement of
   .top-nav itself (relative in Discover's hero, fixed over Levels' trail)
   stays in each page's own stylesheet; this file only styles the burger,
   the dropdown and its rows. Load it after nav-shared.css and before the
   page stylesheet so page-specific overrides still win. */
