How do you advanced design systems people handle type styles(or components) that need variants for both single- and multi-line use cases?

Can you post a photo of what you’re describing?

Hope this does the job 🤷🏼‍♂️ 😁 I'm looking for a best practice, like "go with two dedicated styles" or "make multi-line a prop of the typography component" or ..?

Do you mean that sometimes there's a button where the line-height is 1.4 and sometimes it's 1 but otherwise these buttons work and are used the same?
