/* ============================================================================
   TreeSec — base.css
   DESIGN SYSTEM do site. Carregado por TODAS as 27 paginas, antes de qualquer
   outra folha. Mude aqui = muda no site inteiro.

   Ordem de carga (do geral p/ o especifico):
       base.css  ->  folha de familia (_insight.css)  ->  styles/<pagina>.css
   Por isso uma pagina consegue dar override em qualquer coisa daqui sem
   precisar de !important: ela simplesmente vem depois.
