{{-- M3's search: a search bar that opens into a search view with the results.

     Bind the input like any other (`wire:model.live.debounce.300ms="query"`) and render the
     results in the slot, from a Livewire property or computed property that follows the query;
     `empty` is shown instead when the slot renders nothing (say, "No shares match"). Results are
     usually `<x-list-item>`s with a `link`, or buttons: choosing one closes the view.

     Docked under the bar from `medium` over a scrim, full screen below it with a back arrow
     (resources/css/components/search.css); `docked` keeps it docked at every width. The bar is
     never wider than M3's 720px and grows to that width while it is focused: set `--search-width`
     on a wrapper for a narrower resting bar (M3's own is 360px). `placeholder` ("Search"),
     `label` (the input's name when it differs from the placeholder), leading `icon` (`search`), and
     a `trailing` slot for an avatar or icon buttons in the bar. Every other attribute reaches the
     `<input type="search">`.

     `trigger="icon"` is M3's second entry point, the search icon button: search as a secondary
     action in a toolbar or an app bar, a single 48px button that expands into the full-screen view
     and hands focus to the field (so `docked` has nothing to say about it). The bar itself is the
     view's header there, and closing gives the button its focus back.

     `suggestions` is a slot shown in the view until the first keystroke — M3's suggestions
     behaviour: recent searches, popular queries. The results slot takes over once something is
     typed, and whichever of the two is on screen is what the live region counts.

     The bar is a combobox: the wrapper around the input carries `role="combobox"` with
     `aria-expanded` and `aria-controls`, because ARIA gives a bare textbox neither. The results are
     a list, and a polite live region says how many of them there are whenever they change — M3 asks
     for both (docs/reference/m3/components-navigation-selection-inputs.md § Search).

     The root renders `data-md-search` with `data-md-trigger`, and `data-md-open` and
     `data-md-full-screen` while they hold — `data-md-full-screen` a little longer, through a
     full-screen view's exit back into the bar or the icon (resources/js/search.js); the parts are `data-md-search-*`, drawn by
     resources/css/components/search.css. `class`, `style` and `wire:key` land on the root. --}}
