   auth.css — Portal de acesso
   Moreno Home Conciergeries
   --------------------------------------------------------------------------
   Carregado apenas por login.html. Duas metades:

     esquerda  — a marca: carvão profundo, linhas arquitectónicas ténues,
                 título serifado e a nota do QR Code no rodapé;
     direita   — o acesso: ivory, um contentor de conteúdo estreito com
                 controlo segmentado, campo de código e chamada à ação.

   Tudo assenta nos tokens de variables.css. O champagne aparece só em
   acentos: fio superior, ícones, indicador de idioma e o botão principal.
