+// Night light — a thin wrapper around hyprsunset (0.4.0).
+//
+// hyprsunset is a daemon: `hyprsunset -t <kelvin>` grabs wlr-gamma-control and
+// holds it until it exits, and `hyprctl hyprsunset <request>` re-tunes the
+// running instance over its socket. So the shape here is:
+//   * `active` drives whether the daemon process runs at all,
+//   * temperature changes are pushed to the *running* daemon rather than
+//     restarting it, which would flash the screen back to 6500K.
+//
+// Gamma is restored by the compositor when the daemon's gamma-control object
+// dies, so stopping the Process is a complete "off" — no `-i` pass needed.
+//
+// Only works under Hyprland; there is no gamma protocol on GNOME, so the
+// daemon exits immediately there. That is reported once, not retried.
