/**
 * A real anchor. For in-app navigation a plain click is handled in place, but
 * because it carries a genuine `href`, a middle-click, a modifier-click, or a
 * copied link resolves the way any web link does. `onNavigate` receives the
 * destination for client-side routing. Pass `external` for a link off this app:
 * it opens in a new tab and is left for the browser to follow, since there is
 * nothing to route in place.
