IntelliSense and classes break when initializing shadcn/ui with Tailwind CSS v4

[Mazen-Ahmed-186]

I am running into a significant issue where after initializing shadcn/ui in a project that uses the new stable Tailwind CSS v4, both my Tailwind IntelliSense and the application of classes break.

The problem seems to stem from a conflict between the shadcn/ui CLI's configuration process and the new architecture of Tailwind v4.

I made another project to see what am I doing wrong and walked step by step, once I add shadcn, it breaks all the classes 🙁.

Does someone know the reason? or should I write my classes in a different way after the update?
