<!-- REASONING (not shown to user) -->
1.  **Analyze the Request:**
    *   Task: Extract structured information from unstructured text.
    *   Output format: ONLY valid JSON matching the provided schema. No markdown wrapping.
    *   Schema: `{"people": [{"name": str, "role": str, "email": str|null, "phone": str|null, "mentioned_projects": [str]}], "meetings": [{"title": str, "datetime_iso": str, "attendees": [str]}]}`

3.  **Refine Data Extraction:**
    *   *Karen*: name="Karen", role="CTO", email="karen@acme.io", phone=null, mentioned_projects=["Project Aurora", "Project Lumen"]
    *   *Dan Pham*: name="Dan Pham", role="eng lead", email="dan@acme.io", phone="415-555-0198", mentioned_projects=[]
    *   *Priya*: name="Priya", role="product", email="priya.n@acme.io", phone=null, mentioned_projects=[]
    *   *Meeting 1*: title="sync on Project Aurora and the Q3 migration", datetime_iso="2025-04-22T14:30:00-07:00", attendees=["Karen", "Dan Pham", "Priya"]
    *   *Meeting 2*: title="all-hands", datetime_iso="2025-04-25T10:00:00-08:00", attendees=["Dan Pham"]

4.  **Format as JSON:**
    ```json
    {
      "people": [
        {
          "name": "Karen",
          "role": "CTO",
          "email": "karen@acme.io",
          "phone": null,
          "mentioned_projects": ["Project Aurora", "Project Lumen"]
        },
        {
          "name": "Dan Pham",
          "role": "eng lead",
          "email": "dan@acme.io",
          "phone": "415-555-0198",
          "mentioned_projects": []
        },
        {
          "name": "Priya",
          "role": "product",
          "email": "priya.n@acme.io",
          "phone": null,
          "mentioned_projects": []
        }
      ],
      "meetings": [
        {
          "title": "sync on Project Aurora and the Q3 migration",
          "datetime_iso": "2025-04-22T14:30:00-07:00",
          "attendees": ["Karen", "Dan Pham", "Priya"]
        },
        {
          "title": "all-hands",
          "datetime_iso": "2025-04-25T10:00:00-08:00",
          "attendees": ["Dan Pham"]
        }
      ]
    }
    ```

5.  **Double Check Constraints:**
    *   ONLY valid JSON matching the schema.
    *   Do not wrap in markdown.
    *   Schema types: `str`, `str|null`, `[str]`.
    *   Dates: Today is 2025-04-21. Next Tuesday is 2025-04-22. Friday is 2025-04-25.
    *   Timezones: PT is Pacific Time (UTC-7 in April due to DST). PST is Pacific Standard Time (UTC-8). The text says "PT" and "PST". I will use -07:00 for PT and -08:00 for PST.

6.  **Final Polish:** Ensure no markdown formatting (like ```json) is present in the output. Just raw JSON string.
