/*
ARQUIVO: estilos do hub publico de entrada.

POR QUE ELE EXISTE:
- entrega uma fachada unica, simples e clara para aluno e equipe sem misturar fluxos.

O QUE ESTE ARQUIVO FAZ:
1. desenha o hub /login/ com foco no app do aluno;
2. deixa o acesso da equipe visivel, mas subordinado;
3. reduz ruido visual para a primeira decisao da jornada.
