Theme.json setting not applyed to tailwind classes

Hello,

So I have made settings in the theme.json file, but the settings didn’t create a tailwinnd classes, so I can’t use them. For example I have added a custom font with slug base, but when I want to use font-base, the compiler retrusn error that this class don’t exist.

Here is my theme.json file
