httponly-cookies-invisible-to-document-cookie
Google’s auth cookies (SID, HSID, SIDCC, __Secure-1PSIDTS) are httpOnly and cannot be extracted via document.cookie in the browser Console tab — it returns an empty or partial string. The correct extraction method is DevTools → Network tab → refresh page → click first request to notebooklm.google.com → Request Headers → right-click the cookie: value → Copy value. This is the only reliable method for capturing the full cookie set.
