 2. **Summary (VERY IMPORTANT)**:
    - Write 4-6 comprehensive sentences covering: parties involved, contract scope, key obligations, main coverage/benefits, critical exclusions, important deadlines
-   - Use **Party Name** for persons/entities mentioned
-   - Use **number** for all quantities, dates, amounts, percentages

    - MUST be detailed enough that reader understands contract without opening PDF

-   - Use **bold** for names: {"name": "**John Smith**", ...}
