"""voice ظ€¤ the Smart Advisor voice layer.

Public API (this is the whole contract Fatema depends on):

    from voice import transcribe_audio, synthesize_speech
    from voice import VoiceError            # base error to catch

    transcript = transcribe_audio(audio).text
    audio_path = synthesize_speech(answer_text).audio_path

Async variants (for FastAPI):
    from voice import transcribe_audio_async, synthesize_speech_async

By default everything runs in MOCK mode ظ€¤ no models, no GPU, no API key ظ€¤ so you
can build and test against it immediately. Set the env var VOICE_BACKEND=real
(plus AZURE_SPEECH_KEY / AZURE_SPEECH_REGION) to use Whisper + Azure for real.
