 - `void setEnabled(bool)` - Mute/unmute
-
+- `void applyVolumePreset(VolumePreset)` - Apply Quiet/Normal/Loud preset (configures volume, gate, normalization)
-Loudness is controlled by the system output volume (set via the audio_stream device / Settings UI),
-not by SfxEngine itself -- a fixed app-side gain on top of hardware attenuation gets swamped at low
-system volumes, so there's no separate volume control here.
