/* =========================================================================
   NÚCLEO — folha de estilo única (fundação da interface, Fase 6)

   Sistema de cores/tipografia pensado para o público real do produto:
   famílias cuidando de idosos, muitas vezes com baixa visão, tremor ou
   pouca familiaridade com telas densas (ver 08-acessibilidade-e-inclusao.md).
   Por isso: contraste alto por padrão, alvos de toque grandes, cor nunca
   sozinha como indicador de status, sem depender de fonte externa (evita
   flash de texto sem estilo e falha de rede em conexão doméstica ruim).
