"""Captures P102's browser shots with a real Chromium (run on the Mac after demo.sh):

    /opt/homebrew/bin/python3.14 remotion_shorts/videos/linux-bash-scripting/lab/capture.py

1. report.html, the page Ana's finished script wrote inside the lab container (demo.sh copies it and its
   stylesheet out to lab_out/). It is served from that folder on localhost; the address shown is the file's own
   place on the station box.
2. ShellCheck's public wiki page for SC2086, the warning the tool printed in the demo.
