   Sectro v3 - enxuta. Base da primeira versão (preto puro, Barlow leve +
   pesada com ponto laranja, rótulos com fio, lista de acessos em linhas)
   com o melhor da v2 (números laranja, uma foto por página, palavra no rodapé).
   Coluna estreita, pouco espaço vazio, um raio só: 12px (botões 10px).
