NIGHTS - circadian planning for people who work nights.

You paste the shift roster your employer gave you, and NIGHTS redraws your
next fourteen days as one map: when to get daylight, when to avoid it, when
to stop caffeine, and when to sleep (often two blocks, not one).
Every sleep app assumes you have one bedtime. For the roughly 20% of the
workforce on rotating shifts, that single assumption makes the whole category
useless. The WHO's cancer agency classifies night-shift work as probably
carcinogenic, yet there are dozens of apps that will score your sleep and zero
that will plan it around a roster. NIGHTS is the one that plans.
I wanted it to exist because the countermeasures already do - timed light,
timed darkness, caffeine cutoffs, split sleep - they just live in clinical
papers, not in an app you can open at 4am with one hand. So it is a warm night
sky you can actually read in the dark: deep indigo, glowing amber, soft
hand-painted moons and suns. 24 mobile screens across two flows - a personal
planner, and a shared ward view that stacks six nurses' alertness troughs on
one timeline so a charge nurse can see that four of six hit their low at 3:20am
and stagger the breaks. No consumer sleep product treats fatigue as a team
property. That screen is the heart of it.
Built entirely in Flowstep, driven from the terminal over the Flowstep MCP
server (Claude Code): one DESIGN.md (http://DESIGN.md) pushed as the shared design system, then
every screen generated, simplified, and refined without leaving the IDE.
