  "data": {
    "city": "北京",
    "date": "2026-03-03",
    "restricted": ["4", "9"],
    "isRestricted": true,
    "plate": "京A12345",
    "lastDigit": "4"
  }
}
```

## Example Dialogues

> User: What's today's vehicle restriction in Beijing?  
> Bot: Today's restriction digits: 4, 9 (Your plate 4 is restricted!)

> User: Is my car 京A12345 restricted today?  
> Bot: Yes! Today (Tuesday) Beijing restricts digits 4 and 9. Your plate ends with 4, so it's restricted.

> User: Set a reminder for 7am tomorrow about restrictions  
> Bot: Done! You'll receive a restriction reminder at 7am tomorrow.

## Technical Implementation

1. Fetches daily restriction info from official government sources
2. For Beijing: queries https://jtgl.beijing.gov.cn/jgj/lszt/659722/660341/index.html
3. Parses restricted digits from the official table
4. Compares with plate last digit
5. Sends notifications via scheduled tasks

- Network access (for querying restrictions)
- Message channels (Feishu/Telegram/etc.)
