   URSY.HOSTING — THE FIELD. Copied from URSY.CLOUD assets/css/aurora.css.
   WASHES ONLY, behind a veil, spanning the WHOLE page. Cloud's rule is
   explicit: never orb spheres behind working content. If you can see distinct
   spheres, the implementation is wrong.
   blur(110px) + wrapper opacity .45 is what makes this read as light in the
   room rather than as graphics. hueCycle on the wrapper is "the colour effect";
   theme.js profiles rewrite --o1…--o4 underneath it.
