Amend the Last Commit

Fix the most recent commit without creating a new one.

A beginner Git challenge worth 3 points. Solve it hands-on in a real Git environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: /tmp/repo has one commit (app.py) but you forgot config.py.

Task: Add config.py to the LAST commit with git commit --amend — do not create a new commit.
