openrouter-text2music
Text → music via OpenRouter. Default model: google/lyria-3-pro-preview.
⚠️ This is a music-generation model, not TTS. It produces 48kHz stereo audio with instrumentation, and can include vocals and timed lyrics based on the prompt. For narration/voiceover, use a dedicated TTS tool (e.g., OpenAI tts-1, ElevenLabs).

Notes
- Request uses
POST /api/v1/chat/completions with modalities: ["audio","text"].
- Response parsing handles several shapes:
message.audio, a content part with type=audio, or a data:audio/... URL embedded in the text content.
- Output format is typically WAV (48kHz stereo); the script saves whatever bytes the API returns — choose the extension to match.
