@Aditya948351 , Requesting Review!

[Aditya948351]

It looks like you removed the Navbar, FooterWrapper, and MaintenanceBlocker from the global layout.tsx file while redesigning the login page. This breaks the layout for the entire website! Please revert the changes to layout.tsx and isolate your login redesign to the /login route components.
