## From README

Web Application Testing To test local web applications, write native Python Playwright scripts. Helper Scripts Available: scripts/withserver.py - Manages server lifecycle (supports multiple servers) Always run scripts with --help first to see . DO NOT read the source until you try running the script first and find that a customized solution is abslutely necessary. These scripts can be very large and thus pollute your context window. They exist to be called directly as black-box scripts rather than ingested into your context window.
