  CertChain — sitemap.xml

  Alternates de idioma (xhtml:link) só aparecem onde URLs distintas por
  língua existem (hoje: /about ↔ /sobre). A landing principal (/) usa
  i18n client-side e serve a mesma URL pra todos os idiomas, então não
  declaramos alternates pra ela. Quando rotas /about-es, /about-fr,
  /about-de existirem, replicar o mesmo bloco de xhtml:link para elas.
