/* Elo — telas públicas (login, cadastro, senha, denúncia, enquete, currículo, certificado).
   Mesmo fundo da tela inicial (index.php); o cartão continua claro pra leitura dos formulários.
   Estiliza a marcação que as telas já usam (.auth-card/.cert-card, ícone do topo, card-footer,
   botão Voltar), então cada página só precisa incluir este arquivo. */
