/* =========================================================================
   Base compartilhada dos sites institucionais (PlusInvest e Simples).

   Este arquivo nao contem nenhuma cor de marca: tudo sai dos tokens abaixo,
   que cada site redefine em <site>/css/marca.css. Os valores aqui sao apenas
   fallbacks neutros. Por isso a PlusInvest consegue rodar em tema escuro e a
   Simples em tema claro com exatamente o mesmo CSS de estrutura.

   Regra que vem dos guias de marca: cor de marca cheia (--brand) serve para
   preencher area; cor de marca como texto usa --brand-text, que e a versao
   com contraste suficiente sobre --bg.
