# Hermes' generic sentence splitter treats periods in German abbreviations as
# sentence ends. It also submits every sentence as a separate generative TTS
# request, which creates long gaps with local Qwen3-TTS. Keep the first sentence
# immediate, then group following complete sentences into modest ~240-character
# chunks so playback remains responsive but substantially more continuous.
