The article header pattern is used to display a combinations of overflow menus, breadcrumbs, and page-related actions. It provides a width-flexible space to display information useful to a particular article page or view. It features both the .breadcrumbs and .popover components, and is composed by Atlas's flex atomics.
Please note that, when dealing with a variable amount of breadcrumbs, you'll need to implement some sort of truncation behavior for them.
