      Note that this page is self-sufficient, it does not load any other
      CSS or Javascript file. This is done so because only this page is
      allowed for non-authorized users. If we want to load other files
      from the frontend, we need to change backend code to allow those
      for non-authorized users. See chat.c :: must_authorize() function.
