That is amazing work. You've really plumbed the depths of what's possible with font technology, kudos.

Thank you. Who is really amazing is Simon Cozens, who wrote a set of articles on fonts/global script: https://simoncozens.github.io/fonts-and-layout/

The history of digital fonts added a great deal of complexity to font formats, and without him writing such a concise yet comprehensive guide, I would have been stuck for even longer.
