/* ============================================================================
   CHROME — cabecera, navegación, menú móvil, dropdowns y pie.

   CONTRATO CON EL JS (no renombrar nada de esto sin tocar static/js/):
     main.js        .navbar-toggle · .mobile-menu · .mobile-menu-close · .is-open
                    .navbar-avatar · .navbar-avatar-wrap · .navbar-dropdown
                    .navbar-notifications(-wrap|-dropdown|-badge)
                    .notif-list · .notif-dropdown-empty · .notif-mark-all-read
                    .notif-item · .notif-dot · .is-unread · .notif-content
                    .notif-title · .notif-message · .notif-time   (los crea el JS)
                    #themeToggle · #mobileThemeToggle · #mobileThemeLabel
                    .theme-icon-sun · .theme-icon-moon · .srn-nav-progress
     onboarding.js  #nav-* y #mnav-*
     cookie_consent.js  [data-cookie-preferences] (vive en el pie)

   Tres detalles de comportamiento que condicionan el CSS:
     · .mobile-menu es el OVERLAY, no el panel: main.js cierra comparando
       e.target === menu. El panel es .mobile-menu-panel.
     · main.js pone hidden en el menú tras 300ms, así que la transición de
       salida no puede pasar de ahí (--dur-slow son 290ms).
     · El trampeo de foco filtra por [hidden] y display:none. Nada de ocultar
       con visibility u opacity, o el tabulador entra en controles invisibles.
