/* ============================================================
   STOA / the house style
   Carved stone, with light coming off it.

   Two motion rules govern everything:
   1. The aurora breathes slowly and never stops.
   2. Content arrives as illumination (lit from within),
      never by sliding, wiping or bouncing.

   The aurora is only ever light. Never a full-bleed gradient.
