/* ---------- Surgir ao rolar (confiável: IntersectionObserver) ----------
   Cada bloco surge com leve profundidade quando ENTRA na viewport ao rolar.
   O conteúdo só é escondido quando o JS confirma que vai revelá-lo (classe
   .js-reveal + atributo data-reveal aplicados via JS). Se o JS não rodar, ou o
   navegador não tiver IntersectionObserver, NADA é escondido e tudo aparece
   normal (à prova de "página em branco"). A animação roda para TODOS os
   visitantes, automaticamente, sem depender de configuração nenhuma. */
