/* ============================================================
   AZ Docs — sidebar.css
   O casco das páginas de documentação: navegação lateral fixa à
   esquerda e a coluna de conteúdo à direita. A página ativa se
   identifica com aria-current="page" — o CSS pinta a partir daí,
   sem classe extra para manter em sincronia.
   Em telas estreitas a lateral vira uma barra horizontal no topo.
