I've had Claude make a few static website frameworks for me and I noticed some patterns.
Rounded buttons, serif H1's that are soulful rather than descriptive, two contrasting buttons in the hero, loads of emdashes, "actually's", and hero "scroll down" directions.
While this doesn't check all the boxes, it checks plenty of them. Reading the preview site text makes it seem like a joke. Is this for real???
On the other hand, it is missing the signature emphasis word in italics and a different color.
