Prioritize IDs or specific class combinations that look stable. Return ONLY the selector." 4. **Verify**: - (Optional) Use `run_entry_point` or `screenshot.js` locally with the found selector to verify it captures the correct data. 5. **Report**: Return the found selector to the user or use it in the `add_target` workflow. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/sun-flat-yamada) — claim your Tome and manage your conversions.
