Under active development. A stable version is expected in November 2026. Feedback is very welcome.

See CLAUDE.md for all project conventions, audience profile, exercise requirements, and writing guidelines.

In particular, follow the chapter-structure rules in CLAUDE.md:

• ## Key Takeaways must always use a boxed callout with a numbered summary.
• Add a Common Pitfalls warning box when the chapter has predictable conceptual, practical, or exam-related mistakes worth flagging.
