Concepts for the material's real headings, made in plain code: each heading becomes a
concept named after it, backed by the first two sentences of its section and the first
sentence of up to two more of its passages, so teach-back covers the whole section. A
heading is almost always a main idea, so these do not depend on the model at all.
