/* QBank (v2 da Prova de Equivalencia): configurar, responder e rever, com os tokens do ds/pe.css.
   Tres ecras (.screen): configuracao, pergunta e resultados. A pergunta esconde o
   menu lateral e a barra de baixo da app (body.qb-in-question + pna-sem-tabbar).
   Leitor partilhado: o WOD e os simulados da v2 usam as mesmas classes qb-* (cabecalho,
   cartao da pergunta, opcoes, barra de baixo, folha de respostas, paineis Lab e Nota).
   Cores das areas: .pe-area + --area-cor (areas.cor da BD), tokens --pe-area-* do pe.css. */
