Where you are, and the path back up.

Accessibility

A nav labeled "Breadcrumb" wrapping an ordered list; the current page carries aria-current="page" and isn't a link.
Separators are CSS-generated with the content: "/" / "" alt-text syntax, which keeps them out of the accessibility tree (speak: never is implemented by no browser).
Part of meeting 2.4.8 (Location — AAA).
