Runtime Audio Channels - group SFX for muting, volume, mixer routing and
voice limiting through ScriptableObject channel assets.
The Audio Control Center on the SFX Manager - live per-channel mute and
volume, a global mute, active-voice counts, and a "?" panel that explains the
runtime code API.
Per-character control on the Audio Event Receiver - a muted flag and a
Channel Override, so a player and an NPC sharing the same clip can route to
different channels.
Manual key-triggered playback - Play(key) from code or from the receiver,
running through the same gate pipeline as animation events.
The gate pipeline - playback passes through extensible gates (Mute,
Probability, Cooldown). Add your own via AWSFXManager.AddGate(...).
Per-SFX Play Probability, Cooldown and Priority, plus a per-channel Voice
Limit with steal policies: Suppress, Steal Oldest, Steal Quietest.
