   EBChat — sistema de design "Campanha noturna"

   Escuro por padrão; tema claro derivado da mesma paleta (prefers-color-scheme
   + alternância manual persistida em localStorage, ver js/ebchat.js).

   Camadas deste arquivo:
     1. Tokens (cores, tipografia, medidas)
     2. Ponte com o Bootstrap 5.3 (variáveis --bs-* a partir dos tokens)
     3. Base (tipografia, links, foco, movimento reduzido)
     4. Layout (cabeçalho, rodapé, contêineres, cabeçalho de página)
     5. Componentes (botões, ícones, cartões, passos, campos numerados,
        alertas, estados vazios, FAQ, blocos de comando, figuras, sumário)
     6. Páginas (início, instruções, suporte)
     7. Compatibilidade com as telas legadas de cadastro (até a v3.0)
