/*
ARQUIVO: fachada de login do app do aluno.

POR QUE ELE EXISTE:
- adapta a entrada do aluno para a mesma familia visual do login principal, mas com foco no app.

O QUE ESTE ARQUIVO FAZ:
1. aplica uma cena minimalista e escura para o app do aluno;
2. organiza botoes sociais e acesso da equipe sem competir entre si;
3. limita o escopo ao login do aluno para nao contaminar o resto do app.
