"""Run a build's acceptance checks and print the table the user sees.
    python3 acceptance_run.py <site_dir>                 # against the local build
    python3 acceptance_run.py <site_dir> --url <live>    # against the page actually served at the URL
    python3 acceptance_run.py --selftest
Convention (the fixed part of S5-verify): next to the build lives a checks file,
`acceptance.js` (run with node) or `acceptance.py` (run with python3). It receives one
argument, the path of the HTML to check, and prints one JSON object per line:
    {"id": "5", "check": "自动加速 1000 次更新后速度", "expected": "7.000", "actual": "7.000", "ok": true}
Any other stdout lines are ignored. This script renders the rows as
check / expected / actual / match, adds a one-line verdict, and exits 1 on any mismatch,
so go-live can refuse to proceed. With --url it first fetches the live HTML (and waits
for it to carry the build's rules block, `<script id="rules">`), so what is verified is
what people will actually open, not the local file. Python 3.8+, standard library.
