+The *iconOnly* layout draws only the XStats symbol (plus the keep-awake indicator when active).
+It preserves selected metrics and styles; its 360 pt overview uses the same selection as combined

 Popovers are borderless, non-activating `NSPanel`s. The SwiftUI tree is created on open and
 destroyed on close, so a hidden popover costs nothing. Height comes from measuring a flat,
