class ContactType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('name', TextType::class, ['label' => false, 'attr' => ['placeholder' => 'name']])
            ->add('message', TextareaType::class, ['label' => false, 'attr' => ['placeholder' => 'message']])
            ->add('security', TurnstileType::class, ['attr' => ['data-action' => 'contact', 'data-theme' => 'dark'], 'label' => false])
            ->add('submit', SubmitType::class)
        ;
    }

    public function configureOptions(OptionsResolver $resolver): void
