   Design tokens, reset and typography.

   Palette is drawn from two client assets: the Fiction Factory logo lockup
   (slate and cream) and the printed service flyer (ink, cream and brass).
   Type pairs a slab serif to the typewriter wordmark, a plain reading sans
   for body copy, and a typewriter mono used only for small labels.
