[bug]: Font and other stying is not applying in next application when I create a new project

### Describe the bug When I create a new Next.js project using: pnpm create next-app@latest my-app Environment: pnpm version: 10.23.0 At this stage, the default fonts and styling provided by the Next.js application work correctly. The issue starts after initializing shadcn/ui and adding components using: pnpm dlx shadcn@latest add --all This command successfully initializes the project structure and adds all components to the codebase. However, after that, when I open the webpage, the default fonts and styling are no longer being applied correctly. ### Affected component/components Wholde shadcn ui ### How to reproduce ## Steps to Reproduce 1. Create a new Next.js app. Next.js version: `16.2.6` Run: ```bash id="u1q2m3" pnpm create next-app@latest my-app ``` 2.
