This is some code and config shared by all of my keyboards. I have a few different keymaps spread throughout the repo; however, they are all derived from two "canonical" keymaps for my preferred layouts:

• For typing, my canonical layout is my Crkbd (split ergo, columnar-staggered) layout.

• For gaming, my canonical layout is my Tsangan (row-staggered) layout.
