Review comment (suggestion):
actually, after "zooming out" on the code, I see that we could do this:
```suggestion
            'uploader_id': uploader_id,
            'uploader_url': f'https://{uploader_id}.tumblr.com/' if uploader_id else None,
            **traverse_obj(post_json, {
                # Try oldest post in reblog chain, fall back to timestamp of the post itself
                'timestamp': ((('trail', 0, 'post'), None), 'timestamp', {int_or_none}, any),
```

Code after:
                ('response', 'timeline', 'elements', 0, {dict})) or {}
        content_json = traverse_obj(post_json, ((('trail', 0), None), 'content', ..., {dict}))

        # if it's a reblog, og:description will be the reblogger's comment, not the uploader's.
        # content_json is always the op, so if it exists but has no text, there's no description
        if content_json:
            description = '\n\n'.join(
                item.get('text') for item in content_json if item.get('type') == 'text') or None
        else:
