"""
Take the README screenshots of Wally in every combination:
- the Summary page
- light mode
- 2 viewports: desktop (1280x800), phone (390x844)

Run it against a demo instance (sign-in is off there).
The demo's "Demo. Sample data…" bar along the top is hidden in the shots.
  docker run --rm -e DEMO=true -p 80:80 poliuscorp/wally
  pip install playwright && playwright install chromium
