Extract structured data from unstructured text

Extract data from the text below. Return only valid JSON matching this exact schema, with no commentary, markdown, or wrapping:

```json
{
  "name": "string",
  "email": "string|null",
  "phone": "string|null",
  "company": "string|null",
  "intent": "buy|sell|support|other",
  "summary": "string (max 200 chars)",
  "next_action": "string|null"
}
```

Rules:
- If a field is not present, use null. Do not guess.
- Phone numbers in E.164 (+15555550100). If not possible, null.
- "intent" must be one of the four listed values.
- "summary" is a one-sentence description in your own words.
- Always return valid JSON. Never wrap in ```.
