Add a demo mode to the app that bypasses auth and loads mock data, so the app works flawlessly during a hackathon presentation without needing a real account or live backend. Use when the user says "set up demo mode", "make it work without login", or "I need it to look good for the judges".

Generate and run realistic seed data for the project's database. Use when the user says "seed the database", "add some fake data", "I need test data", or the app looks empty during a demo.

Work on the liquor_store_agentic_monitor hackathon demo — agentic multimodal retail POS monitoring (mock CV/ASR + POS fusion), Streamlit UI, policy tuning, segments JSON, webhooks, deploy.
