# /compare is not listed here on purpose. It carries `noindex, follow` and it is linked
# from every page that shows the compare tray — a crawler blocked here would never reach the
# noindex, and a disallowed-but-linked URL can still surface in results with no snippet.
# One signal, and it is the one on the page.
