/**
 * Horizontal application menu bar (Apple/Windows app style).
 *
 * @description
 * A dense top-row menu architecture designed for data-heavy or media-editing
 * web applications (IDEs, document editors). Each `<MenubarMenu>` renders
 * as a trigger with a nested dropdown.
 *
 * @ai-rules
 * 1. Do NOT use Menubar as a replacement for `<Tabs>` navigation — it is for command menus, not page switching.
 * 2. `<MenubarShortcut>` renders hotkey labels — do not change its typography.
 * 3. For simple action menus (user profile, row actions), use `<DropdownMenu>` instead.
