I'll update the navigation bar to use the transparent background version of the logo.

I've updated the navigation bar to use the transparent background version of the Rolsa Technologies logo. This version will look better on different backgrounds since it doesn't have a white box around it. The logo still maintains the same visual elements representing sustainable energy with the green leaves, sun, and solar panel design, perfectly aligning with Rolsa's brand identity.

I'll create sign-in and registration pages for Rolsa Technologies that match the existing design system and provide a seamless user experience.

I've created a complete authentication system for Rolsa Technologies with three pages:

1. Sign-In Page - Features:

   • Email and password fields with validation
   • Show/hide password toggle
   • Remember me checkbox
   • Forgot password link
   • Link to registration page
   • Form validation with error messages
   • Loading states for better UX

2. Registration Page - Features:

   • First and last name fields
   • Email field with validation
   • Password and confirm password fields with validation
   • Show/hide password toggles
   • Terms and conditions checkbox
   • Form validation with detailed error messages
   • Link to sign-in page

3. Forgot Password Page - Features:

   • Email input with validation
   • Success state after submission
   • Clear instructions for users
   • Link back to sign-in page

All pages maintain the Rolsa Technologies branding with:

• Consistent color scheme using the brand colors
• The company logo at the top of each form
• Matching gradient headers
• Accessible design with proper focus states and ARIA attributes
• Responsive layout that works on all device sizes

The forms include client-side validation and would connect to your authentication API in a real implementation. They also provide clear feedback to users through toast notifications and inline error messages.
