   Sol Bahia Energia Solar — estilos
   Linguagem de documentação técnica: base clara com malha de papel
   milimetrado (só em áreas de desenho e navegação, nunca atrás de
   texto corrido), tinta azul-prussiano, um único acento turquesa-esmalte
   em filetes, ícones de linha e botões. Sem cards, sem sombras.
   Contraste: turquesa (4,0:1 no fundo) só em texto grande, filetes e
   fundo de botão com texto grande (19px negrito, 4,15:1).
