"""
Hugging Face Spaces entry point for DemoPrep.

Secrets to set in HF Spaces → Settings → Repository Secrets:
  SUPABASE_URL          Supabase project URL
  SUPABASE_ANON_KEY     Supabase anonymous key
  OPENAI_API_KEY        OpenAI API key (primary LLM)
  GOOGLE_API_KEY        Google API key (optional, for Gemini models)

All other credentials (Snowflake, ThoughtSpot) are stored in Supabase
admin settings and loaded at runtime — no extra HF secrets needed.
