   FÓRUM MANUFATURA 5.0 — mesma identidade visual do portal

   O visual segue o eiv.ia.br, igual ao portal: fundo azul royal,
   conteúdo em cartões BRANCOS sólidos (não translúcidos) e títulos
   em caixa mista (não em caixa alta condensada).

   Se mexer aqui, confira se o portal precisa da mesma mudança —
   os dois precisam continuar parecendo o mesmo produto.
