/* Central de Ajuda pública — herda a identidade da landing (creme + laranja, display Bahnschrift,
   corpo em serifa). Arquivo compartilhado, e não estilo embutido como no index.html: são 11
   páginas, e uma cópia por página divergiria na primeira alteração.

   Sem webfont, igual à landing: as famílias são as do sistema operacional, então a página pinta no
   primeiro frame e não pisca texto. */
