      # 22.04 ships Python 3.10, which cannot install the pinned Django (it
      # needs >= 3.12). While requirements.txt still said "django>=4.2" that
      # went unnoticed and pip quietly resolved a 4.x here — so CI was testing
      # a different Django than the image actually shipped. 24.04 gives us
      # 3.12, matching the Dockerfile's python:3.12-slim.
