# actually performs: register an admin, invent a post type in the wizard, and
# for each content post type build a topbar series, confirm it lands in the
# nav, add a child post and confirm the child renders on the series page.
#
# Verification goes through Trog::Routes::HTML::index() -- directly, or via
# series() which delegates to it -- and matches on the returned HTML.
