Extract the description and a list of guests from the supplied episode notes from a podcast.

  Also provide a Dewey Decimal Classification code and label for the description

  Return valid JSON conforming to the following Typescript type definition:

  {
    "description": string,
    "guests": {"name": string, "affiliation": string | null}[]
    "dewey_decimal": {"code": string, "label": string},
  }

  Episode synopsis (Markdown):

  {notes}

  Valid JSON:

- Typescript definition (turn raw html markup >> well-formed JSON)

- Dewey Decimal classification/score

So probably combination of those two
