   Escrito para este case. Prefixo pr- em todas as classes.
   Os estados iniciais das animações só valem quando o prumo.js
   adiciona a classe pr-a-* no <html>; se o script falhar, tudo
   aparece pronto. Controles que dependem de JavaScript só existem
   com a classe pr-js.
   O app (telas e protótipo) está em prumo-app.css.
