Tweak size/position for your layout.\n- **Polling Interval:** `Wait` node amount is **2** (seconds). Increase if you hit rate limits; decrease for faster checks.\n- **Safety:** The GPT prompt enforces **no text/logos** in the generated image—keep this to avoid artifacts.\n- **Dimensions:** Final canvas is **800×500** (web article hero size). Adjust in `resize image` if your site uses a different aspect ratio.\n- **Error Handling:** If status never becomes `COMPLETED`, add an `If` branch for timeouts or retries.\n"
