Dockerfile

# HF Spaces removed the Streamlit SDK (create_repo now accepts only gradio|docker|static),
# so the Space runs as a Docker image that serves the same single Streamlit process.
FROM python:3.12-slim

# Spaces serve on 7860 and run the container as uid 1000. The app writes at runtime
# (embedded Qdrant store, accounts SQLite), so the tree must be owned by that user.
