I've got to come back in here and update the sort for the axes. It should be sorted by always usable, with a secondary sort for a heading use. I'm not sure exactly why the previous sort order doesn't work for this chart

AH! it's because they're one way (not all FG->BG exists for every BG->FG)

TODO: demo the actual FG/BG example (rather than the white text on token color)

Todo: turn the validation list into a real, functional, textarea component

TODO: 1. infer global tokens from the original token structure (eg. only create 1 button for "social.facebook") 2. parameterize the remaining "themed" tokens 3. make all other diagrams flow their values from this cell
