Nice list of design patterns, but imo a big unmentioned one is a grid of rounded rects https://correctarity.com/roundedrects (maybe what this post calls "Icon-topped feature card grid." ...that might be the official design pattern term)
Cards have been in vogue for a while and I can’t recall the last time I saw super hard corners on a design system. It’s been a thing since at least Apple filing that patent on rounded corners.
I don't think it's just the base rate of rounded corners though, these posts feel like the AI tends to spit out a bullet point list of features, like you'd see on an AI readme where each feature has a tangential emoji, then for a website puts them in a grid of rounded rects
