aws-samples/streamlit-application-deployment-on-aws — reverse-engineered prompt

Build me a Python Streamlit app for exploratory data analysis that business users can log into and use to explore financial CSV data without needing to write SQL.

It should be able to run locally with a simple Streamlit command, and it should also include scripts to deploy everything to AWS. Use S3 for the uploaded flat files, Glue to crawl the data, Athena to query it, and show the results visually in the dashboard. Include a sample data loader that pulls Yahoo Finance market and forex data so the app works right away.

For the cloud setup, make it secure with Cognito login and host the Streamlit app on AWS behind a load balancer, using the AWS services needed to package and run it reliably. Please include clear setup steps, sane config defaults, and a cleanup script so I can remove the AWS resources when I’m done. Look up current AWS docs online if you need to.
