/* ============================================================================
   ATELIER — Aditya Kumar Gupta
   ----------------------------------------------------------------------------
   Art direction: warm obsidian and brass. Bodoni Moda (Didone) against Jost
   (geometric sans). Hairlines instead of borders; light instead of glow; zero
   radius everywhere. Data is set as ruled ledgers and numeral plates rather
   than cards, because cards are what everyone else does.

   Layer order (z):
     0  WebGL canvas .......... fixed, alpha, behind everything
     2  page content .......... opaque sections sit over the canvas
     3  aura + graticule ...... cursor light, blended over content
     4  grain ................. tactile surface, over everything but the cursor
     60 masthead / to-top
     99 cursor
