#
# Why Docker (vs. HF's `sdk: streamlit`): the HF web UI's new-space picker
# doesn't expose Streamlit as a first-class SDK choice anymore (only
# Gradio / Docker / Static are listed). Docker SDK is the cleanest way to
# keep our Streamlit UI exactly as-is without migrating to Gradio.
#
# Build behavior matches the offline-replay-only Space:
# * No torch / transformers / sentence-transformers — we ship the KB
# embeddings cache and `ui/app.py` only imports light deps.
# * Cold-start ~30-60s on HF's CPU-basic tier.
# * Default Streamlit port is 7860 on HF (NOT 8501 — HF expects 7860).
