docs: // IndentedJSON serializes the given struct as pretty JSON (indented + endlines) into the response body.
  // It also sets the Content-Type as "application/json".
  // WARNING: we recommend to use this only for development purposes since printing pretty JSON is
  // more CPU and bandwidth consuming. Use Context.JSON() instead.
