Thanks.

But fyi for others this is one version behind and missing these updates:

  V1.3 (May 12, 2026)
  Many typos and phrasing fixes with the help of LLMs.
  Section 3.8. Added a section about large-scale training

Oh, that's unfortunate! I made it from the A5 version on the site which I downloaded right before making my post. Looks like the author hasn't updated that one.
