§ 01 — A thought

A textbook ends. A study guide answers a question. A library holds a mind.

§ 02 — Unfolded

Every resource we publish is a small, self-contained object — a chart, a deck, a chapter guide — and part of one continuous surface. Read it once. Return to it in three months. It's still yours.
