May I ask whether “suls” here refer to thuluth ثلث? From what I read, the name can be romanized as thuluth, sols (Persian), sülüs (Turkish), and so on. I am not familiar with “suls” option and thought that thuluth would be more commonly understood English romanization for the style.
Since there is multiple way to render this, perhaps which romanization to be used should be considered to avoid confusion.
