-doc: Embed YouTube videos, with foldable captions. The `levelOffset` parameter can be used to control the depth of the video heading and content. The shortcode can be invoked either with an `id` attribute, or by specifying `page`. In the latter case, that page's preamble should provide `youtube_id`, `title`, `venue`, and `date`, and its contents act as the video transcript. Remember the closing tag!
