"""Chromium regression against PHP-rendered preview HTML and real app assets.

Export HTML from the disposable HTTP suite with MAINTENANCE_PREVIEW_HTML,
then run: python3 tests/acct_maintenance_browser.py /path/to/preview.html
Requires playwright and its Chromium browser. Network requests are intercepted;
this tests real browser rendering/JS, not live login or native autofill.
