+ * 2. Go to the script settings and enter your GitHub Personal Access Token
+ *    (create one at https://github.com/settings/tokens — fine-grained
+ *     with "Models: Read" permission, or a classic token)
+ * 3. Once the script is active, you can choose the "GitHub" backend and
+ *    your preferred model
