Now I'll update both components to use React Hook Form with proper TypeScript types:

I've successfully integrated React Hook Form with complete TypeScript types into both components. Here's what was added:

Sign In Component:

• SignInFormInputs interface with email field
• SignInResponse interface for API responses
• Full form validation (email required, email pattern validation)
• Error and success message states
• Input error messages displayed below fields

Sign Up Component:

• SignUpFormInputs interface with fullName, email, and password fields
• SignUpResponse interface for API responses

• Comprehensive validation rules:

  • Full name: 2-50 characters
  • Email: valid email format
  • Password: minimum 8 characters with uppercase, lowercase, and numbers
• Real-time validation feedback with error messages

Both components now use useForm hook with TypeScript typing, proper error handling, and aria-invalid attributes for accessibility. All console logs are preserved for debugging.

Now I'll update the Sign In component to show the proper message after successful submission:

I've updated the Sign In component to show a proper email link message after submission. The success message now displays "Check your email" with the text "We've sent a sign-in link to [user's email]. Click the link in your email to sign in." This provides clear feedback to users that they need to verify their email address.
