docs: // Normalize - if successful this makes the model JSON serializable.
  // Without this, if the object was created with e.g. a YAML parser,
  // the type of `opts` might be map[interface]interface, which is not JSON serializable.
  // After this call it's ensured that the type of objects is map[string]interface,
  // which is JSON serializable.
