[bug]: Build fails with TS2307: Cannot find module '@/components/ui/card'

Describe the bug

Description

The project fails to build because TypeScript cannot resolve shadcn/ui component imports.

Error

src/pages/ActivityLog.tsx(5,59): error TS2307: Cannot find module '@/components/ui/card' or its corresponding type declarations.

## Solving the problem
I solved the problem Capitalizing the name in the file as Card.tsx

### Affected component/components

Card, Sidebar

### How to reproduce

Clone the repository.

Install dependencies:

npm install

Run:

npm run build
Observe the TypeScript errors.

I checked this against the shadcn/ui registry and CLI output. The generated component path is already lowercase components/ui/card.tsx, and the documented import is @/components/ui/card.

This looks like a local project casing or alias configuration issue rather than a bug in shadcn/ui. On case-sensitive build environments, the file name and import path must match exactly.

[LazyCoder11]

Yeah, agree with Yngesh, CLI output is lowercase, so this isn't a shadcn bug.

@hanbit10 heads up though: renaming to Card.tsx "fixes" it locally because Windows is case-insensitive, but Vercel builds on Linux which is case-sensitive. So this could still break on deploy even if it builds fine on your machine.

Probably better to keep the file lowercase card.tsx and check if there's a duplicate file or stale cache causing the conflict instead.

Also forceConsistentCasingInFileNames: true in tsconfig.json would catch this earlier next time.

Looks like a local config issue, not shadcn/ui itself.
