   Stelor admin — the site's own stylesheet

   The look is the Stelor admin console's, written out for a page that stands on
   its own: the same colours, buttons, inputs, badges and dialog. The two
   screens bring the rest of their styles with them.

   Served to anybody (the sign-in page needs it). It holds no data. */
