/* ============================================================================
   Sistema visual — Plataforma de Contratos, Grupo Castel

   É o mesmo sistema do Signal (signal-os/frontend/src/control/signal.css):
   papel quente, uma barra lateral escura que flutua como cartão, folhas
   brancas de canto largo separadas por tom e sombra suave — não por fio —,
   cobre como único acento, e a fonte do sistema em tudo. Rótulos em
   maiúsculas pequenas no sans, nunca em monoespaçado: o mono fica reservado
   ao número, que é a única coisa que precisa de alinhar em coluna.

   A versão anterior (serifa no título, mono maiúsculo nos rótulos e botões,
   cartão com fio de 1px) era a assinatura que a cliente leu como "feito por
   IA". Este ficheiro troca a pele; as classes são as mesmas.
