+-- 022: Exam Preparation Module
+--
+-- Generic exam preparation infrastructure parameterized by exam_key.
+-- Supports multiple exams (math9, phys9, chem9, math11ce, etc.) sharing
+-- the same task bank, attempts tracking, mock sessions, and study plans.

+-- See docs/exam-prep-plan.md for full architecture.
