/* Lonebird site — shared shell.
   -------------------------------------------------------------------------
   The palette is lifted straight from the game's dawn biome (lib/game/palette.dart)
   so the site and the first thing a player sees are the same place. Type pairs a
   quirky variable grotesque for display with a serif for prose: the legal pages
   are the ones people actually read, and a serif at a comfortable measure reads
   like a document rather than like a dashboard. */
