In our studies of ChatGPT's grammatical style (https://arxiv.org/abs/2410.16107), it really loves past and present participial phrases (2-5x more usage than humans). I didn't see any here in a glance through the lightfastness section, though I didn't try running the whole article through spaCy to check. In any case it doesn't trip my mental ChatGPT detector either; it reads more like classic SEO writing you'd see all over blogs in the 20-teens.

edit: yeah, ran it through our style feature tagger and nothing jumps out. Low rate of nominalizations (ChatGPT loves those), only a few present participles, "that" as subject at a usual rate, usual number of adverbs, etc. (See table 3 of the paper.) No contractions, which is unusual for normal human writing but common when assuming a more formal tone. I think the author has just affected a particular style, perhaps deliberately.
