/*
  Alcance — tela de entrada.

  Copia fiel da tela de login do Sistema-Geral (frontend/pages/auth/css/Login.css):
  mesmo cartao de 440px, mesmos espacamentos, mesmos raios, mesmas sombras, mesma
  animacao de entrada. Quem usa os dois sistemas precisa reconhecer o Alcance na
  primeira olhada — por isso NADA aqui foi "melhorado".

  As unicas diferencas em relacao ao original, e o porque de cada uma:
    - marca Alcance (SVG inline) no lugar da logo da outra empresa;
    - sem webfont: o CSP e `default-src 'self'` e o Inter vinha de CDN. Fica a pilha do
      sistema — que e exatamente para onde o original tambem cai quando a CDN nao responde;
    - sem "Registre-se", sem "Esqueci a senha", sem "Voltar ao site": o Alcance tem um
      unico usuario, criado por linha de comando, nao tem recuperacao de senha e nao tem
      site institucional. Link que nao leva a lugar nenhum e pior que link nenhum.
