/* =========================================================================
   Bone Valley homepage (v3, coming soon). Loads after site.css; the Depot,
   store and 404 pages use site.css alone.
   Direction: one piece of key art, plain prose, and one printed Amberline
   application on paper as the page's single moment of personality.
   Spacing stays on the site.css scale: 8, 16, 24, 40, 64, 96, 160.
