Study mode

Study turns the board into a review deck. Quote cards and claims become cards, in either direction: source → passage ("what does this author say on page 132?") or passage → source ("whose words are these?").

Nothing is generated. A card is your own pinned text shown back to you, so a deck can never teach you something your sources do not say.

Grade each card Again, Hard, Good, or Easy and the interval adjusts. Due cards come first, then ones you have not seen. Your review schedule is yours alone — two people studying the same shared workspace keep separate progress.
