Build hypothesis
ShiftNight is a focused validation signal: a small audience can still value a highly specific planning workflow without pretending to diagnose sleep.

- Show sleep windows, wind-down, and caffeine cutoffs on one timeline
- Use careful wellness language and keep health data private by default
