"""HF Spaces (ZeroGPU) entry point: Peitho 1.5B v6 German voice demo.

Background: the stock LFM2.5-Audio-1.5B base model is English-only for
speech-to-speech (see https://huggingface.co/LiquidAI/LFM2.5-Audio-1.5B —
"Supported languages: English"). Our v6 fine-tune is what teaches it German
audio output. A short A/B with the unmodified base model produced garbled
German + robotic audio — confirming the fine-tune is essential.

Model loading + the German v6 overlay live in `peitho_model.py`, which is
written to be boot-safe on ZeroGPU (no CUDA warmup at import). This entry
point just imports the model, then launches the chat demo.
