The Science of SleepShift

1. Sleep Anchoring: We anchor wake-up times to your Prep & Commute window.

2. Roster Flip Logic: The algorithm detects break length.

3. The 90-Minute Rule: We calculate a necessary wind-down period.

4. Adenosine Management: We identify the "Danger Zone" where sleep pressure is highest.

5. The Caffeine Cutoff: We calculate the 6-hour half-life of caffeine.
