+/// A view controller may conform to `PathIdentifiable` to expose the URL it represents.
+///
+/// `Navigator` uses this URL — instead of view-controller type equality — when deciding
+/// whether a proposed visit refers to the page already on top of the stack or to the page
+/// directly beneath it. Without this conformance, two instances of the same custom view
+/// controller class but with different URLs are indistinguishable to the navigator and may
+/// be incorrectly popped or replaced.
+///
+/// `Visitable` inherits from this protocol, so existing visitable view controllers satisfy
+/// it automatically via `initialVisitableURL`.
