It really is super clever! And the crazy part is that it's been possible for a super long time, just nobody thought of the technique. Mad props to Riley Cran and the entire crew at https://lettermatic.com for devising this technique as a part of this project.
I'm curious: did the team consider applying the technique to letter pairs like Ty and TA that traditionally get kerned closer together in proportional fonts?
As far as I can tell from the demo, these pairs currently aren't affected by texture healing, and they look a little awkward in Radon especially.
