- MENTAL_CLARITY: +10% study speed when mana > 75%
- STUDY_RUSH: First hour of study is 2x speed
- STUDY_MOMENTUM: +5% study speed per consecutive hour (max +50%)
- KNOWLEDGE_ECHO: 10% chance for instant study progress
- STUDY_REFUND: 25% mana back on study completion
- Add tracking for studyStartedAt and consecutiveStudyHours
- Reset tracking when study completes or stops
