   Por que um arquivo separado do style.css do site:
   o style.css carrega o design system inteiro da home — preloader, canvas de
   partículas, cursor luminoso, blocos que só aparecem quando o main.js roda.
   Documento legal não pode depender de JavaScript: se o script falhar, o texto
   tem que estar lá. Aqui é só tipografia, e nada esconde nada.

   As variáveis são as MESMAS do style.css, copiadas de propósito para a página
   se sustentar sozinha. Se a marca mudar de cor, mude nos dois lugares.
