/**
 * Audio-driven mouth animation addon for xrblocks. The primary export,
 * `LipsyncMouth`, is a small `xb.Script` that pulls audio from a
 * `MediaStream`, runs an FFT + formant-based viseme mapper on it every
 * frame, and writes the viseme weights to a `setVisemes`-compatible
 * target — typically the `face` on a netblocks `RemoteUserAvatar`, or
 * a standalone `xb.StylizedFace` for non-multiplayer use.
 *
 * The face primitive itself (`StylizedFace`) and the viseme contract
 * type (`VisemeWeights`) live in xrblocks core so neither addon has
 * to depend on the other.
 *
 * @see {@link LipsyncMouth}
