/* navbar.css — mega-menu dropdowns (Roadmap / Guides / AI Assistants).
 *
 * Deliberately a separate file rather than part of common_styling.css.
 * common_styling.css is pre-cached cache-first by the service worker
 * (see static/sw.js APP_SHELL), so editing it leaves returning visitors on the
 * previous deploy's copy until their worker updates. This file is not in
 * APP_SHELL, and the worker only ever writes to its cache during install, so
 * requests for it always miss the cache and go to the network - nav styling
 * therefore updates on the very next load after a deploy.
 *
 * Keep nav/dropdown styling here, not in common_styling.css.
 *
 * These rules are shared by the hero nav on the home page and the wavy navbar
 * on every inner page, so both look like one system. Hero-only pieces
 * (.mega-menu-sidebar, .sidebar-item, .content-*) live in index_styling.css.
