features/desktop/nightlight.nix previously set
`services.hyprsunset.enable = lib.mkDefault true` unconditionally and
baked the temperature (4000K when toggles.nightlight, 6500K otherwise)
into extraArgs at Nix-eval time. The toggle script bypassed systemd:
pkill on disable, `hyprctl dispatch exec hyprsunset --temperature 4000`
on enable — racing the systemd-managed instance and hardcoding 4000K
regardless of nomarchy.nightlightTemperature. The "Always enabled, we
control via IPC and state" comment was misleading: no IPC, the
temperature was rebuild-time, and the script forked a parallel
process.
Path (b) from the Later row:
- services.hyprsunset.enable now follows config.nomarchy.toggles.
nightlight — symmetric with services.hypridle.enable ← toggles.idle.
Disabled toggle = no process running.
- extraArgs always reads from config.nomarchy.nightlightTemperature.
Drops the 6500K neutralising fork; when off the unit just doesn't
start.
- nomarchy-toggle-nightlight flips the running systemd user unit via
`systemctl --user start/stop hyprsunset.service` for instant
feedback, reads nightlightTemperature from state.json for the
notify-send line, and writes .nightlight back to state.json so the
next rebuild realigns services.hyprsunset.enable.
`nix flake check --no-build` + `bash -n` clean.
- Reorganize directory structure into core/, features/, and themes/
- Colocate application Nix logic, configs, scripts, and theme overrides
- Implement 'Inversion of Control' for theming: apps now pull theme-specific layouts
- Update flake.nix and shared library paths to match the new structure
- Document the new Feature-Centric architecture in README.md
