/* ============================================================================
   Padrão visual Atsun — apps de HTML único com tema escuro
   (Controle de Usuários, Server Monitor, MultView).

   ⚠️ Arquivo IDÊNTICO nos três projetos (web/atsun-padrao.css). Ao mudar um,
   copiar pros outros. Carregado DEPOIS do <style> de cada página, então
   estas regras prevalecem sobre as antigas do mesmo seletor.

   Espelha o padrão dos apps React (Selfstorage/Financeiro/Controle de
   Acesso): barra superior com marca da empresa à esquerda, abas no meio,
   engrenagem de Configurações + menu do usuário (avatar) à direita; tela de
   login SEMPRE clara (card de 340px, faixa de destaque de 4px no topo,
   logo grande + nome + rodapé de crédito Atsun); "Sobre" com a logo oficial
   da Atsun em 80×80, cantos arredondados.

   Usa as variáveis do tema escuro de cada app: --bg, --panel, --border,
   --text, --muted, --accent, --err.
