{{--
    Campo de um bloco do catálogo no editor da home (P5.S2.1 — emenda ADR-016).

    - O rótulo e o vocabulário do campo vêm do **catálogo** (`layout::blocks.fields.*`): o mesmo
      texto serve Home e Páginas sem duplicar tradução.
    - `$oldValue` já vem resolvido pelo chamador (`old($errorKey, $value)`), então um erro de
      validação não apaga o que o operador digitou.
    - O erro é sempre server-side (`$errors`), mostrado junto do campo e referenciado por
      `aria-describedby`; o resumo `role="alert"` é do formulário (`x-cms::form-errors`).
    - Nada de HTML/Blade/CSS no dado: só controles nativos; texto rico é AST (ADR-028) e mídia é
      **id** do catálogo (ADR-026).
    - Campo **traduzível** (P5.S2.2) abre um grupo com um controle por locale (pt_BR/en/es/fr); o
      nome vira `campo[locale]` e o mapa é validado pelo schema do tipo (texto/AST). O locale
      default é o fallback do portal quando um idioma não for traduzido.

    @var BlockField $field
    @var string $name       nome do input (ex.: `sections[0][props][title]`)
    @var string $errorKey   chave no error bag (ex.: `sections.0.props.title`)
    @var string $id         base dos ids do campo
    @var mixed  $oldValue   valor corrente (old() já aplicado)
