# How the apex behaves.
#   serve    (current) the apex is a SECOND Pages custom domain and answers 200.
#            No redirect rule, no placeholder record. The pages emit
#            canonical=www, which is what consolidates the two hosts for search.
#   redirect the apex 308s to www. Kept because the assertion is cheap to keep
#            and the decision could be revisited; nothing sets it up any more.
