Implement Client-Side Form Validation for Signup Flow2

Project Overview: We need a frontend developer to add robust, real-time client-side validation to our multi-step user registration forms to improve user experience and data integrity. Expected Output: - Real-time validation for email formatting, password strength requirements, and matching passwords. - Inline, user-friendly error messages that appear immediately when a field loses focus (onBlur) or when invalid data is typed. - Disabling the "Submit" button until all required fields pass validation checks. Required Skills: - JavaScript (ES6+) / ReactJS - Experience with form libraries like Formik, React Hook Form, or custom Yup validation schemas - Clean CSS/Tailwind styling for active, error, and success states Important Details: The static UI inputs and layouts are already complete. Your role is purely to inject the validation logic and style the error state triggers cleanly.
