Pages are imported parents first, each child with parent_id, so nested
addresses build as they were. A parent the old site didn't have becomes
an overview page or a draft (the user's choice). Slugs are unique per
site and language, since a page is found by its address's last part:
clashes get another slug and a redirect. Netflex parents now come from
the old url, so a folder in the address becomes a page instead of being
dropped; Statamic checks each collection's route.
