/* ==========================================================================
   Darcy's Stacks

   Two colours carry the room: midnight navy for air and forest green for
   matter. Brass is the only accent and it is rationed. There is one typeface,
   Archivo, served locally, and the width axis does the expressive work.

   The canvas is owned rather than decorated: one colossal solid word behind
   the collection, one light source that answers the pointer, and one animated
   object per view. No patterns, no textures, no borrowed backgrounds.
