# Night light — a scheduled blue-light filter via hyprsunset (Hyprland's own
# gamma/temperature tool). Warm at night, identity (no shift) by day;
# hyprsunset's time-based `profile` entries handle the schedule and pick the
# right state on session start. Opt-in via nomarchy.nightlight.enable.
#
# The hyprsunset HM service module is provided by home-manager; this only
# configures it. Override anything with plain services.hyprsunset.* options.
