Names the fields of a model that carry the tenant's further languages. The attribute
declares; {@see \LaravelUi5\Sdk\I18n\Concerns\HasTranslations} acts — it reads
these fields in the request's language and writes them through {@see \LaravelUi5\Sdk\I18n\TranslationWriter}.
#[Translatable(['title', 'description'])]
final class Item extends Model
{
use HasTranslations;
}
The base language stays in each field's column; the further languages live in sdk_translations.
Provisional until the first real multilingual project in Switzerland.
