Night light is off by default and configured entirely through the menu,
writing into the downstream flake instead of ~/.local/state — so the
choice is git-tracked and reproducible across a clone+rebuild.
Two flags under a new settings.* section of the state file (exposed as
the nomarchy.settings option):
- settings.nightlight.installed — sticky, gates the hyprsunset unit;
nomarchy.nightlight.enable mkDefault-reads it. First enable from the
menu rebuilds to create the unit (the one accepted rebuild).
- settings.nightlight.on — runtime on/off, toggled instantly
(theme-sync set --no-switch + systemctl), no rebuild. An ExecCondition
reads the live flag at session start so an off survives reboot;
splitting it from the sticky flag means a later unrelated rebuild
never undoes an instant-off (no decay).
Drops the ~/.local/state/nomarchy/nightlight-off marker and the
ConditionPathExists hack. theme-sync set now skips the wallpaper
re-apply for non-wallpaper keys, and its rebuild notifications are
generic ("changes" not "theme").
First cut of the broader principle — any user-settable config gets a
menu writer that lands it in the flake; no state outside the checkout.
Docs (README §4, ROADMAP, template) updated to reflect it.
Eval- and round-trip-verified; on-hardware check pending.
