  <li>
    <details>
      <summary><code>&lt;|fans:text={text}|&gt;</code></summary>
      References the fanbase of the talent.

    </details>
  </li>
  <li>

      References another talent by their name or one of their nicknames.

      <code>other</code> is the full canonical name of the referenced talent.
      <code>text</code> is the original text, encoded as base64.
      <code>aff</code> is the affiliation of the other talent. This has two values - <code>org</code> (meaning the referenced talent is affiliated with the same organization as the stream host) and <code>none</code> (meaning the referenced talent is from another organization).
    </details>
  </li>
  <li>
    <details>
