"""Phase 5 acceptance test against the LIVE deploy of oscar-web.

Exercises every scenario S1-S10 from cms/tests/acceptance/site-smoke.test.js
in a real browser via Playwright. Each scenario is self-contained: starts
with a clean localStorage, runs the actions, asserts the expected
post-conditions, and captures a screenshot.

Outputs:
  - One screenshot per scenario: /workspace/projects/oscar-web/metrics/phase5/S<n>-<name>.png
  - Final JSON summary written to /tmp/phase5-results.json
  - stdout PASS/FAIL per scenario

The script uses the **public** API of the CMS module loaded as ES modules
from https://oscar-web.pages.dev/admin/ — same code path operators use.
