   Restored editorial site skin

   The containment pages keep their current legal and operational content, but
   share the same visual language as the restored "Da pergunta à publicação"
   landing: white paper, navy ink, restrained blue accents and serif headings.
   These shared tokens and compatibility rules preserve the existing semantic
   markup and legal copy. The final cascade at the end of this file reasserts
   the component skin after the former dark-site rules.
