Show a plain form field's errors under its name
Fields read their errors only under the wire:model name, so a Fortify
login form (name="email", no wire:model) never showed "These
credentials do not match". Without wire:model they now read the name,
turning brackets into dots.

{{-- A file picker, in the text field's chrome (resources/views/components/field.blade.php).
M3 has no file field, and building one would redo what the browser's input already does the
picker, a file dropped on it, the keyboard, what a screen reader announces, the `change` a
Livewire upload listens for. So the input stays native, its label always floats (the button
stands where a resting label would), and only its `::file-selector-button` is restyled: a tonal
pill, so it reads as the thing to press (resources/css/components/field.css).
The browser's own line beside the button ("No file chosen", "3 files") is drawn transparent:
it cannot be truncated or wrapped, and the caller shows what was chosen anyway, as previews. A
screen reader still hears it. The errors are the model's and, for a `multiple` input, each
file's (`photos.*`): a file refused for its size belongs under this field as much as the
batch's own count does. `label`, `hint`, `variant`; every other attribute reaches the `<input>`. --}}
@props([
'label' => null,
'hint' => null,
'variant' => null,
])
@php
$model = $attributes->whereStartsWith('wire:model')->first();
$id = $attributes->get('id') ?? 'field-'.substr(md5('file|'.$model.'|'.$label), 0, 12);
// A plain form's field is named, not bound: its errors are under its name (`files[]` → `files`, `a[b]` → `a.b`).
$errorKey = $model ?? (filled($attributes->get('name')) ? str_replace(['[]', '[', ']'], ['', '.', ''], (string) $attributes->get('name')) : null);
$messages = $errorKey !== null && isset($errors)
? array_values(array_unique(\Illuminate\Support\Arr::flatten([$errors->get($errorKey), $errors->get($errorKey.'.*')])))
: [];
