# Production runtime requirements (Hugging Face Spaces / Docker).
# Version ranges aligned with the dependency tree used by ``lightweight-embeddings``
# so Gradio, FastAPI, Starlette, Pydantic and Jinja2 all interop cleanly on
# Spaces. Keep in sync with ``[tool.poetry.dependencies]`` in pyproject.toml.

# Optional UI extras.
# Gradio 5.x is required for compatibility with modern Starlette templating;
