This page handles OAuth2 authentication callbacks for the SE Event Navigator Tampermonkey script.
The callback receives the access token from Google and passes it back to the userscript.
This page is hosted on GitHub Pages and serves as the OAuth2 redirect URI for Google Drive API authentication.
When users enable Drive sync in the SE Event Navigator, they authenticate via Google OAuth, and the access token is returned to this callback page, which then forwards it back to the userscript.
- This page contains no secrets or credentials
- The access token passes through momentarily and is never stored
- Only authorized users logged into their Google accounts can complete the OAuth flow
