Review comment (refactor):
I think we should raise here if we don't find anything. Better than an IndexError later imo
```suggestion
        blocks = traverse_obj(art_json, (
            'sprinkledBody', 'content', ..., ('ledeMedia', None),
            lambda _, v: v['__typename'] in ('Video', 'Audio')))
        if not blocks:
            raise ExtractorError('Unable to extract any media blocks from webpage')
