{{-- A select: the native `<select>`, drawn as M3's exposed dropdown menu.

     Native on purpose: the keyboard, type-to-find, the screen reader and the form value are the
     browser's, and `wire:model` binds to it as to any select. Where the browser has the
     customizable select (`appearance: base-select`) its open list is M3's menu, under the field
     and as wide (resources/css/components/menu.css); elsewhere the native list stands in. So the
     options stay plain text: the native list could show nothing more. A select always shows a
     value, so its label always floats.

     `options` as a list of `['id' => …, 'name' => …]` (`'disabled' => true` greys one out),
     `option-value` and `option-label` to read other keys, and a `placeholder` that becomes the
     first option, valued `placeholder-value` (empty by default). Or pass `<option>`s in the slot.
     `label`, `hint`, `icon`, `variant`, `size`; `class` and `style` land on the field's root, every
     other attribute on the `<select>`. The field's root carries `data-md-select`; what a
     select changes in the field's chrome is resources/css/components/select.css. --}}
