The question bank is seeded locally from the source booklet and stored in the browser database. When a session starts, the page draws the correct answer plus additional distractors from the wider bank for that topic, then randomizes the display order.
This summary is withheld until the session ends so the question flow stays neutral during the attempt.
The source PDF still lives in this page unchanged, so layout, numbering, and diagram references remain tied to the attached booklet.
The browser seeds a local practice database now, and the repo also carries generated SQLite/SQL outputs so the same bank can move into a server-backed platform.
Practice mode randomizes answers without adding prompt hints, coaching copy, or mid-question feedback that steers a student toward the key.
