▸case-01 Here is a function in `orderStatus.ts` modified in this session:
```ts
function getStatusMessage(status: string, role: string): string {
return status === 'pending' ? (role === 'admin' ? 'Pending Approval' : 'Pending Review') : status === 'approved' ? 'Order Approved' : 'Unknown Status';
}
```

▸case-02 I edited `schemas/user.ts` in our pull request. We currently have:

email: z.string().email(),
role: z.enum(['admin', 'user'])
});
export interface User {
id: string;
email: string;
role: 'admin' | 'user';
}
```

export function UserProfile({ user }: { user: User }) { ... }
