Ddey07/wc2026-hydration-momentum ? reverse-engineered prompt

Build me a reproducible analysis project that tests whether the 2026 World Cup hydration breaks affected match momentum.

I want a notebook driven workflow that loads the provided match data, rebuilds the analysis from start to finish, and regenerates all tables and figures for a paper. The main question is whether the mandatory breaks around the 22nd minute of each half made the dominant team lose momentum, or whether any drop was just a normal return to the mean after the stoppage. Please include the two within match comparison approaches, a simple external control comparison, and a check using expected goals too.

The finished project should be easy to run locally, not need internet during the main analysis, and write outputs into the paper folder. If some match momentum data has to be fetched from the public source again, include a script for that and make it clear how to rerun it. Keep the code organized so the notebook can execute the whole thing end to end without manual steps.
