/* ---------------------------------------------------------------------------
   Found To Fixed — foundtofixed.com

   ⚠ The brand tokens are NOT defined here any more. They live in
   brand/tokens.json and are generated into theme/static/css/tokens.css by
   `make brand`. That file is linked before this one, so every var() below
   resolves against it.

   The reason they moved: the website is not the only thing that consumes the
   brand. A slide deck, a Word document and an Inkscape file need the same
   values, and a palette that lives in a stylesheet can only be copied into
   those by hand — which is how a deck ends up a shade off the site. One source
   of truth, several generated consumers, and `make check` fails if they drift.

   Contrast is measured, not estimated, and it is recomputed at build time
   rather than transcribed into a comment: see brand/dist/CONTRAST.md and the
   `contrast.pairs` list in brand/tokens.json. Changing a colour that breaks a
   pair fails the build.
