Aadarshttech/azure-ai-capstone ? reverse-engineered prompt

Build me the Track A version of this Azure AI capstone in Python, a simple app that answers questions from my own documents and shows the source for each answer.

I want it set up so I can add documents, run an index or retrieval step, then ask questions and get grounded responses with citations. Use Azure OpenAI or Foundry models plus Azure AI Search, and keep the secrets in a .env file with a clear .env.example. Please include a clean starter structure, a working main script or notebook, and a README that explains how to set it up and run it. Add a few sample documents or sample inputs if needed, and make sure the output is easy to understand for a non expert.

If there are any current Azure setup details that matter, look up the latest docs online if you need to. Also include a short note about one risk or limitation, like hallucinations or weak citations, so the project is ready to demo.
