   Camada NEUTRA: tokens de estrutura, reset, tipografia, layout e os
   componentes genéricos (botão, chip, formulário, sanfona, abas, preço).
   Não tem cor de marca: as cores vêm do TEMA (projeteam.css), que redefine
   os tokens --brand-*, --ink-*, --bg-* etc. Para o site da Devnture, este
   arquivo vai inteiro e só o tema muda.
