"""What netOrk's discovery scores the driver on.

netOrk lowercases the page (title, Server header, body) and matches each rule's pattern as
a substring; a port that answers adds its PortSpec weight. AMT names itself in its
``Server`` header on every answer, also the 401 of a page that needs a login.
