# Voice deps (faster-whisper, kokoro, torch, soundfile, spacy) are NOT
# installed in the production image. They added ~2 GB and pulled numpy<2,
# which has no cp314 wheel and broke the slim-image build.
# Voice paths in code are lazily guarded; with VOICE_ENABLED=false (default),
# the app starts cleanly. With voice enabled, missing imports log and
# the feature gracefully degrades. To re-enable voice in a build, install
# the `voice` extra: `pip install .[voice]` — and add an extras step here.
