eddychetz/lab_59_cust_lifetime_py ? reverse-engineered prompt

Build me a small Python app for exploring customer lifetime value from a dataset.

I want to be able to load customer data, calculate lifetime value for each customer, and see a simple summary of the results in a clean app. It should show useful charts so I can understand which customers are most valuable and how the values are spread out. If there are any missing or messy fields, handle them gracefully and don’t crash.

Use the sample data in the project if that helps, and make the app easy to run from the main file. If you need to look up current docs online for anything, go ahead. I’d also like the analysis code to be separated cleanly from the app UI, so it’s easy to reuse later.

Please make the experience straightforward, with a simple page or window, a few clear inputs if needed, and readable output that a non expert could understand.
