## Behavioral Rules

- `date` is optional and uses `yyyy-MM-dd`
- default `pageNo` is `1`
- default `pageSize` is `10`
- use the returned structure as-is

When presenting results, summarize the day's important items in chronological order.

When explaining this feature to the user, describe it as a daily overview that can cover things like:
- people recommended in discover
- chats involving the user
- the user's Plaza activity
