   Timber Squirrel — style.css
   Direction: "Norse twilight forest, lantern-lit". Organic and grounded, with
   one amber accent doing all the work. Display type is an old-style serif
   (Iowan / Palatino) so the saga reads like a saga; body and HUD are a humanist
   sans; every number is monospaced so the par counter never jitters.
