Layouts
Sharing UI between multiple routes using Layouts.
Learning Goals
The Core Concept
A Layout is a UI component that is shared across multiple pages. When a user navigates between pages, the layout preserves its state, remains interactive, and does not re-render. A 'layout.tsx' file wraps all the 'page.tsx' files inside its folder and subfolders.
