User task -> Is it static HTML?
     Yes -> Read HTML file directly to identify selectors
              Success -> Write Playwright script using selectors
              Fails/Incomplete -> Treat as dynamic (below)
    
     No (dynamic webapp) -> Is the server already running?
         No -> Run: python scripts/with_server.py --help
                Then use the helper + write simplified Playwright script
        
         Yes -> Reconnaissance-then-action:
            1. Navigate and wait for networkidle
            2. Take screenshot or inspect DOM
            3. Identify selectors from rendered state
            4. Execute actions with discovered selectors
