danielsaed/futbol_corners_forecast ? reverse-engineered prompt

Build me a football corners forecast app that predicts the total number of corners in a match from historical team data.

I want it to let me enter two teams, the season, the round, and the league, then return a corner prediction plus a simple over and under style confidence view and a reliability score. Please also include the full data pipeline so it can collect or load match stats, clean them, create the engineered features, train the model, and save the best version. A small web interface would be great, and if it makes sense, expose the prediction through an API too.

Use the existing data and model files if they are there, and keep the app focused on football betting style analysis. Make the results page easy to read, with the main prediction, likely corner range, and a few useful probabilities. If you need current docs for any library details, look them up online and keep iterating until it runs cleanly.
