{{-- An M3 Expressive menu: a list of actions that opens from a trigger.

         <x-menu label="Share actions">
             <x-slot:trigger>
                 <x-button icon="more_vert" tooltip="More" />
             </x-slot:trigger>

             <x-menu-item label="Copy link" icon="content_copy" wire:click="copy" />
             <x-menu-separator />
             <x-menu-item label="Delete" icon="delete" wire:click="delete" />
         </x-menu>

     The trigger's first button or link becomes the menu button (aria-haspopup, aria-expanded,
     aria-controls). The list is a `popover="auto"` in the top layer, placed by CSS anchor
     positioning at `position` (`bottom-start`, `bottom-end`, `top-start`, `top-end`) and flipping
     when there is no room; a click outside or Escape closes it. The keyboard is WAI-ARIA's menu
     button: Enter, Space or ArrowDown open on the first item, ArrowUp on the last; arrows, Home,
     End and typing a letter move between items; Tab closes; activating an item closes the menu
     unless the item says `keep-open`, and Escape returns focus to the trigger.

     The container is Expressive's standard menu (surface-container-low, 16px corner, elevation
     2), or `vibrant` in tertiary-container — StandardMenuTokens and VibrantMenuTokens from
     androidx Compose Material 3 (Apache-2.0). --}}
