   login.css — acesso ao painel, 2026-09-07.

   Direção: editorial + operacional. A tela usa os mesmos tokens/temas do
   painel, mas sua composição é própria: contexto da Central, uma pequena
   pauta de áreas e o formulário em etapas. O cartão é opaco e legível; o
   ambiente, não o conteúdo, recebe textura e profundidade.
