    a primary function and have predefined fallback actions or secondary
    functions if the initial attempt fails. It supports error handling
    with a customizable failure threshold, which allows retrying on specific
    exceptions.

    :param func: The primary function to execute.
    :param fallbacks: A list of tuples where each tuple contains an exception type and a callable that acts as a fallback.
    :param max_retries: Maximum number of retries allowed before giving up. Default is 3.
