🚀 Learn how to build a **clean, type-safe login form** for your **JobPortal** app using **React Hook Form** + **Zod** validation in **Next.js**!

In this step-by-step tutorial we:
✅ Remove boilerplate code from the login UI
✅ Add `useForm` with the **Zod resolver**
✅ Register every input field (`email`, `password`)
✅ Show **real-time error messages** (required, pattern, minLength)
✅ Validate on the **frontend** before hitting the API
