/* =============================================================
   Gestão de Sócios — direção visual "Terminal Nocturno"
   -------------------------------------------------------------
   Escuro por omissão (a identidade da app). Fundo quase preto
   azulado, um único acento ciano usado com parcimónia, números
   e identificadores em tipo monospaçado. Continua a ser uma
   ferramenta de trabalho séria — só que noturna.

   Temas (alternador na barra de topo: sistema → claro → escuro):
   - :root                          → escuro (identidade, também no modo "sistema")
   - [data-theme="light"]           → variante "dia" (opção explícita do utilizador)
   - [data-theme="dark"]            → escuro (opção explícita)

   --accent  = ciano decorativo (foco, separador ativo, ações primárias)
   --danger / --stamp = negativos (cotas em atraso, saídas, erros, remoções)
