How we keep measurements honest
Tab-switch voids the round
Leave the tab mid-test and the attempt is discarded, not scored.
Sub-80ms is a prediction
Humans can't react faster than ~80ms. Faster taps are flagged and excluded.
Input dedup at 100ms
Double-taps and macro bursts can't inflate a reading.
