/* Reggenza Engenharia - site institucional, versao 3.
   A paleta e a tipografia sao da marca (deck institucional v5): tinta quase-
   preta, papel off-white, dourado unico como acento - isso nao muda.
   O que muda aqui e a estrutura: fotografia em tela cheia em vez de caixas
   com padding, tipografia bem maior e mais confiante, e poucos momentos de
   movimento bem orquestrados em vez de "fade-up" em cada card. */
