### Runtime Type Safety
TypeScript types disappear at compile time. **Zod** parses unknown JSON data at runtime, throwing structured errors or returning guaranteed types:

``

typescript
const UserSchema = z.object({
  id: z.string().uuid(),
  role: z.enum(["admin", "member"])
})
type User = z.infer
