Evening routine
- Wind-downLast caffeine 8+ hours before bed; finish large meals 3+ hours before.

- DevicesBlue-light filters and lowered brightness; park notifications after wind-down starts.
Aligning with dual n-back
- Best windowTrain when alert: 1–4 hours after waking or 4–6 hours after; avoid late-night sessions.
