CNToolbarButton: A toolbar button: an icon or a text label, with an optional badge.
CNToolbarInspectorToggle: The standard button that shows and hides the window's inspector (NSToolbarItem.Identifier.toggleInspector, macOS 14+).
CNToolbarInspectorTrackingSeparator: Lines the items after it up with the window's inspector (NSToolbarItem.Identifier.inspectorTrackingSeparator, macOS 14+).
CNToolbarItem: An item of a CNToolbar.
CNToolbarMenu: A toolbar button that opens a menu.
CNToolbarSearch: The search field of a window toolbar (NSSearchToolbarItem, macOS).
CNToolbarSegment: One segment of a CNToolbarSegmentedGroup.
CNToolbarSegmentedGroup: A group of segments in the toolbar, such as view modes or filters.
CNToolbarSidebarToggle: The standard button that shows and hides the window's sidebar (NSToolbarItem.Identifier.toggleSidebar, macOS).
CNToolbarSidebarTrackingSeparator: Lines the items before it up with the window's sidebar, so they sit over the sidebar and the rest over the content (NSToolbarItem.Identifier.sidebarTrackingSeparator, macOS).
CNToolbarSpace: Empty space between toolbar items.

CNToolbarGroupRole: What a CNToolbarSegmentedGroup is for, which macOS 27 shows with a look of its own (NSToolbarItemGroup.Role). Earlier systems and iOS draw every group the same.
CNToolbarItemStyle: The look of a CNToolbarButton.
CNToolbarSelectionMode: How the segments of a CNToolbarSegmentedGroup are selected.
CNToolbarStyle: How the window toolbar of a CNToolbar is laid out on macOS.

debugResetCNToolbarWindow() → void: Forgets every shown toolbar, so each test starts from a window without one.
debugResolveToolbarItemIds(List<CNToolbarItem> items) → List<String>: The id CNToolbar gives each of items in its payload and its events: the item's own CNToolbarItem.id, or its kind and its index among the items of that kind (button#0, menu#1).
