/**
 * Optional PCM playback engine entry (`@runtypelabs/persona/voice-worklet-player`).
 *
 * A jitter-buffered AudioWorklet player for raw PCM16 / 24 kHz / mono streams,
 * kept out of the main bundle. Two ways in:
 *   - `createPcmStreamPlayer({ prebufferMs })` — general primitive with
 *     pause/resume; reuse it inside a hosted `SpeechEngine` (server/ElevenLabs/
 *     OpenAI TTS) for gapless "Read aloud".
 *   - `createWorkletPlaybackEngine` — realtime-named alias; pass it to
 *     `voiceRecognition.provider.runtype.createPlaybackEngine`.

// AudioPlaybackManager, so the engine no longer depends on the worklet — but it
// pairs naturally with `createPcmStreamPlayer` above (pass it via
// `createPlaybackEngine`) for jitter-buffered playback. Most integrations don't
// import it directly — `textToSpeech: { provider: 'runtype' }` wires it
// automatically; this export is for manual `textToSpeech.createEngine` control.
