[Bug]: Browser back button not working properly when navigating from /learn to main page

Summary

Problem: When navigating from http://localhost:3000/learn to a specific learning page (like Quick Start), clicking the browser's back button does not return to the main page at http://localhost:3000/ .

Steps to Reproduce:

1. Go to http://localhost:3000/learn
2. Click on "Quick Start" (or any other learning section)
3. Click the browser's back button
4. Expected: Should return to http://localhost:3000/
5. Actual: Does not navigate back to main page

Browser: Chrome

Page

http://localhost:3000/learn

Details

Additional Context: This appears to be a navigation history issue where the browser's back button functionality is not working as expected when moving between the main page and learning sections. The issue might be related to how Next.js handles client-side routing in the learning section.

Possible Related Issues:

• Similar to the fragment link back button issue that was recently fixed
• May involve scroll restoration or navigation state management

Start by reproducing the flow from /learn to Quick Start and back to the main page in Chrome. Then inspect the learning section's Next.js client-side routing and compare it with the recently fixed fragment-link navigation. Done means the browser back button returns from a learning page to http://localhost:3000/ as expected.
