  let fittedSize = clampToDisplay(idealSize, displayBounds: displayBounds)
  return WindowPlacement(size: fittedSize)
}
.windowIdealPlacement { content, context in
  let idealSize = content.sizeThatFits(.unspecified)
  let displayBounds = context.defaultDisplay.visibleRect
  let zoomedSize = zoomToFit(idealSize, displayBounds: displayBounds)
  let position = centeredPosition(for: zoomedSize, in: displayBounds)
  return WindowPlacement(position, size: zoomedSize)
}
```
