jet-lag-protocol-planner@1.0.0

Publisher claims: "Use when crossing 2+ time zones: computes your day-by-day circadian shift protocol — pre-trip sleep shifting, light SEEK/AVOID windows timed to your core-body-temperature minimum, low-dose melatonin timing, caffeine cutoffs, and in-flight/first-days rules for east and west travel." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
