- Full library home page: question list with per-user mastery stats,
search/source filter, sort (A-Z, weakest first, most-seen), source
breakdown in header, Take a test CTA.
- GET/POST /questions/{id}: view and edit question text, source, answers;
radio-select correct answer; shows seen×/correct% stat.
- POST /questions/{id}/delete: hard delete (cascades to answers via FK).
- repo: ListQuestions supports SortWeakest/SortMostSeen via LEFT JOIN;
added CountBySource, UpdateQuestion, UpdateAnswers, DeleteQuestion.
- render: added pct template func (correct*100/seen).
