The class name max-w-208 is invalid. Should be max-w-[52rem] (original value).

The class name max-w-400 is invalid. Tailwind CSS doesn't have a max-w-400 utility. This should likely be max-w-[100rem] (which was the original value) or another valid max-width utility.

The class name conversion from bg-gradient-to-t to bg-linear-to-t is incorrect. In Tailwind CSS v4, gradient utilities still use the bg-gradient-to-{direction} format. This should be bg-gradient-to-t.

The class name size-140 is invalid. Tailwind CSS doesn't have a size-140 utility. This should be size-[35rem] (the original value).

Alot of stuff shifted around (padding, offsets, etc.)
But the site seems functional and everything looks close enough to how it was.
Didn't really look at the code too much, just the rendered site.
Updates all of the NPM dependencies including:
It is preferable for reviewers to check out the branch locally and run the site to compare it to the live version rather than just reviewing the code. Many fixes are done by the tooling.
