Ah, see that at least sounds plausible. I've used Google Translate to translate road signage with the camera, and it tries to position and resize text to fit the original sign. So if that kind of technology is happening here, that could make some sense.

...but then why wouldn't you just let the browser translate it for you, since it would normalize the same font size across the entire text? Oh, if they were in the Threads app they wouldn't have they available.
