Re-activation = time from releasing a key to pressing the same key again.
HOW TO TEST
1. Rapid tap — tap a single key as fast as possible for 10+ seconds
2. Rollover — press and hold 6+ keys simultaneously (both hands)
3. Rapid trigger — if your keyboard has RT, tap with minimal finger travel
4. Export — download the full report as JSON for offline analysis
