One-line: what a list looks like before it has anything in it — always name the next action.

```jsx
<Empty>
  <EmptyHeader>
    <EmptyMedia><CalendarIcon /></EmptyMedia>
    <EmptyTitle>No bookings yet</EmptyTitle>
    <EmptyDescription>Share your link and the first one will show up here.</EmptyDescription>
  </EmptyHeader>
  <EmptyContent><Button>Copy booking link</Button></EmptyContent>
</Empty>
```
