   * FRONTENDS, however they must never be destroyed if already in the data.
   *
   * the `extensions` properties may contain arbitrary key-value pairs, but you are encouraged
   * to namespace the keys to prevent conflicts, and you must never destroy
   * unknown key-value pairs from the data. `extensions` is mandatory and must
   * default to `{}`. `extensions` exists for the character book itself, and for
   * each entry.
