Each session ends with a saved Notebook artifact in the learner’s own words (with v1/v2 revisions) and a calm Daily Passport check-in. Use the Atlas for short theory, key terms, and text-only timelines or place/climate facts, then complete guided Studio Runs with self-check and reflection. Review Lab builds focus sets from local mix-ups and saves Revision Cards for later review.
