## What are Barrel Files?

Barrel files are index files (index.ts/tsx) that re-export modules from a directory, allowing cleaner imports:

**Before:**

```typescript
import { UserService } from "./services/user/UserService";
import { AuthService } from "./services/auth/AuthService";
import { Button } from "./components/ui/Button";
```

**After:**

```typescript
import { UserService, AuthService } from "./services";
import { Button } from "./components/ui";
```
