/* GrainFed — no framework, no build step, one stylesheet.
   The site is built the way the software is.

   The palette is the logo's: one hot orange, one near-black, and white. Orange
   is for things you can press and for marks of emphasis; it is never body text,
   because orange text on white does not reach a readable contrast. Where text
   sits on orange it is black, which does. */
