Separate the navbar from the root layout, keeping the root layout clean. Create two child layout folders:
1. main: for basic layouts such as the navbar
2. clean: for clean layouts without any extra elements.
Completely refactoring the entire old codebase with a new codebase. This change also altered most of the core UI from the old codebase, replacing it with Shadcn with some customizations.
The reconstruction includes moving the Navbar component from shared to widget because Navbar is a group of elements, and
removing the login-signup form due to changes in logic that will use a popup flow to improve the user experience without
navigating to another page for authentication.
