   A logo é a imagem enviada pelo Adilson, não uma recriação.

   São dois arquivos gerados a partir do mesmo PNG original:
   - assets/logo.png       cores originais, para fundo claro
   - assets/logo-dark.png  verdes escuros clareados, usado aqui

   No arquivo original o "reen" e o "energy" são verde-escuro (#005424), feito
   para fundo branco. Sobre o azul-petróleo do header o contraste é de 1,6:1,
   ou seja, praticamente invisível. Na variante escura esses tons vão a 6,1:1. */
