How a chapter is sized

One chapter is one idea taken to the point of use

Each chapter is a single self-contained explainer of 8 to 10 narrated minutes, covering one idea to the point where you can use it.

Chapters run in order. Each one assumes only what the chapters before it taught, and capability belonging to a later course is named and deferred rather than half-covered.
