# Core dependencies for TTS Audiobook Generator
gradio_client>=0.7.0
pypdf>=4.0.0

# Optional dependencies — features degrade gracefully without them
# (tagged "# optional:" so the env bootstrap can skip them on platforms
# with no compatible wheels instead of failing the install)
beautifulsoup4>=4.11.0  # optional: better HTML cleaning for EPUB (stdlib fallback)
faster-whisper>=1.0.0  # optional: reference-audio transcription (falls back to x-vector-only cloning)
windows-curses>=2.3; sys_platform == "win32"  # enables the TUI on Windows
