# Minimal dependencies for the HOSTED DEMO and the deterministic core.
#
# This is the file Streamlit Community Cloud auto-detects. It installs only what the
# Design Calculator + Optimize Ratio modes need, so the demo boots in seconds and stays
# well under the free-tier resource limit. Chat mode degrades to a friendly message.
#
# For the FULL stack (chat / RAG / pluggable LLM backends / Telegram / tests that import
# langchain + faiss), use `requirement.txt` instead.
