    """Custom DRF exception handler that catches all otherwise-unhandled exceptions.

    DRF's built-in handler only converts a small set of framework exceptions
    into API responses. Any other exception propagates as a 500 HTML error page.
    This handler intercepts those cases, logs them, and returns a generic
    ``APIException`` response so callers always receive a structured JSON body.

    Args:
        exc: The exception raised during request processing.
        context: DRF handler context dict (contains ``view`` and ``request``).

    Returns:
        Response: A DRF Response for the given exception, or a generic 500
            response when the exception is not natively handled by DRF.

    # a tiny subset of exceptions). In this case, just log the error and
    # return generic error response.
