  Syncs LeetCode browser cookies to the VS Code LeetCode extension running on localhost. This extension helps LeetCode VS Code users securely sync their LeetCode sessions with the extension, eliminating manual cookie copying.

  LeetCode VS Code Auth Sync
  
  Unofficial companion browser extension for LeetCode with Auth Sync. It is not affiliated with, endorsed by, sponsored by, or published by LeetCode.
  
  Tired of manually copying and pasting your LeetCode session cookies into VS Code? This extension automatically and securely syncs your active LeetCode.com session to the LeetCode with Auth Sync VS Code extension.
  
  How to use it:
  1. Install the VS Code extension: https://marketplace.visualstudio.com/items?itemName=wilmtang.vscode-leetcode-auth-sync
  2. Install this Chrome extension on the same machine.
  3. Sign in to https://leetcode.com/ in Google Chrome.
  4. In VS Code, click LeetCode: Sign In and choose Auto Cookie Sync.
  5. Click Sync now in this extension's popup, or simply use LeetCode normally and wait for automatic sync in the background.
  
  How it works:
  The VS Code extension starts a local listener on your machine (at 127.0.0.1:17899). This Chrome extension reads your active leetcode.com cookies and sends the LeetCode Cookie header directly to that local listener, where VS Code reuses the existing cookie login flow.
  
  Privacy and Security:
  Your cookie values are sent only to the local VS Code listener on your own machine. They are never intentionally logged, stored remotely, or transmitted to any third-party servers.
  
  Source Code & Contributions:
  This extension is fully open-source. You can view the source code, report issues, or contribute to the project on GitHub at:
