 @description "Idle management for Moonarch (Niri + moonlock)"
 
 default:
-  # Media playback inhibits idle. Browsers expose MPRIS during video playback
-  # and only send D-Bus idle-inhibit in fullscreen, so we include remote media
-  # to catch windowed browser videos.
+  # monitor_media: detect active media via PipeWire/PulseAudio sink-inputs
+  # (pactl), not MPRIS. Non-browser players (mpv, vlc, ...) are counted and
+  # inhibit idle. Browser audio is excluded by design; browser idle-inhibit is
+  # expected via D-Bus (enable_dbus_inhibit), which Waterfox/Firefox only send
+  # in fullscreen -- so windowed browser video is NOT caught by stasis.
+  # ignore_remote_media false: also count remote players (Spotify-remote,
+  # KDEConnect, Chromecast); has no effect on windowed browser video.
