# hyprsunset (the blue-light filter) is gated on `nomarchy.toggles.nightlight`
# so a disabled toggle means no process runs — symmetric with how
# `services.hypridle.enable` is wired off `toggles.idle`. The temperature
# comes from `nomarchy.nightlightTemperature`, evaluated at Nix-eval time
# and baked into `extraArgs`. The toggle script (themes/engine/scripts/
# nomarchy-toggle-nightlight) writes both the toggle and the same
# temperature value into state.json and flips the systemd unit for
# instant feedback; the next rebuild's HM activation realigns systemd
# with the persistent state.
