class StealthConfig:
    """
    Playwright stealth configuration that applies stealth strategies to playwright page objects.
    The stealth strategies are contained in ./js package and are basic javascript scripts that are executed
    on every page.goto() called.
    Note:
        All init scripts are combined by playwright into one script and then executed this means
        the scripts should not have conflicting constants/variables etc. !
        This also means scripts can be extended by overriding enabled_scripts generator:
        ```
        @property
        def enabled_scripts():
            yield 'console.log("first script")'
            yield from super().enabled_scripts()
