Hi @Ashmita1206 👋

I would like to work on this improvement under SSoC'26.

I can integrate the newly designed logo into the navbar while maintaining consistency with the current UI theme and responsiveness across devices.

Proposed Improvements:

• Add the new gradient logo to the navbar
• Ensure proper alignment and spacing on all screen sizes
• Maintain responsiveness for mobile and desktop layouts
• Optimize logo sizing and visibility for better branding consistency
• Ensure favicon/logo integration matches the existing design system

Please assign this issue to me.
Thank you!
