Code Block Max Height

Set a fixed height for code blocks with scrolling.

Usage

```ts {2|3|7|12}{maxHeight:'100px'}
function add(
  a: Ref<number> | number,
  b: Ref<number> | number
) {
  return computed(() => unref(a) + unref(b))
}
/// ...as many lines as you want
const c = add(1, 2)
```

With Line Highlighting Placeholder

Use {*} when you only need maxHeight:

```ts {*}{maxHeight:'100px'}
// long code here
```

Use Case

When code is too long to fit on one slide but you want to show it all with scrolling.
