{{-- An M3 Expressive FAB menu: a FAB that opens into a short list of related actions.

         <div class="fixed end-4 bottom-4">
             <x-fab-menu label="New">
                 <x-fab-menu-item label="Upload files" icon="upload_file" wire:click="uploadFiles" />
                 <x-fab-menu-item label="Upload a folder" icon="drive_folder_upload" wire:click="uploadFolder" />
             </x-fab-menu>
         </div>

     Two to six items. The FAB (`icon`, `add` by default, in `color`'s container) turns into a
     round close button in the colour itself while the list is open above it, end-aligned; the
     list is a `popover="auto"` menu with the menu keyboard of `<x-menu>`. `label` names the FAB
     for screen readers. Give the items the same `color`. Like `<x-menu>`'s, the list is keyed for
     Livewire, so it stays open through a render of the component around it.

     FabMenuBaselineTokens (androidx Compose Material 3, Apache-2.0): 56px items, 4px apart, 8px
     above the close button. The FAB's corner and colours morph on the two default springs at once
     (`state-transition-default`, resources/css/components/actions.css). --}}
