 * The Books icon + flyout injected by custom.js reuse the platform's own
 * classes (menu__nav-item, menu__nav-submenu, menu__nav-submenu-item, _active),
 * so they inherit the native styling. These rules only guarantee the few
 * behaviours we drive ourselves render correctly regardless of platform CSS.
