The entire website is fairly small so this seems feasible.
Usually there’s a big difference between a website’s final code and its source code because of post processing but that seems like a totally solvable Claude problem.
Sure LLMs aren’t great with images, but it’s not like the person who originally wrote the Space Jam website was meticulously messing around with positioning from a reference image to create a circular orbit — they just used the tools they had to create an acceptable result. Claude can do the same.
Perhaps the best method is to re-create, rather than replicate the design.
