/**
 * Adds a keyboard-accessible nested menu to a `MenuContent` panel.
 *
 * Use `MenuSubmenu` when an action needs a second level of choices. React Aria
 * manages focus, pointer interaction, arrow-key navigation, and `Escape`
 * dismissal; Unity adds the submenu caret to the trigger item automatically.
 * @param props - React Aria submenu behavior and the two-part composition.
 * @param props.children - Exactly two children: the trigger `RawMenuItem`,
 *   followed by its `MenuContent`.
 * @see {@link MenuSubmenuProps} for all available props.
 * @example
 * ```tsx
 * import {
 *   MenuContent,
 *   MenuSubmenu,
 *   RawMenuItem,
 * } from '@payfit/unity-components'
 *
 * <MenuContent>
 *   <MenuSubmenu>
 *     <RawMenuItem>Share</RawMenuItem>
 *     <MenuContent>
 *       <RawMenuItem>SMS</RawMenuItem>
 *       <RawMenuItem>Email</RawMenuItem>
 *     </MenuContent>
 *   </MenuSubmenu>
 * </MenuContent>
 * ```
 * @remarks
 * Nest another `MenuSubmenu` inside the child `MenuContent` to create deeper
 * levels. Add a `suffix` to the trigger item when it also needs a badge or
 * other trailing content; Unity displays it before the submenu caret.
