/* The door of a hosted papo: the pages iu serves before anyone is in — entering,
   a first access and its code, waiting for the Crachá to answer. They come
   from iu with its class names (iu-login, iu-signin, iu-acesso, …) and no look
   of their own: each application dresses them. This is papo's, in papo's
   colours. The selectors go by the parts of the names, so that a page iu adds
   later is dressed too. */
