The Deaf zone printed "Deaf (affinity bloc A017)" as its title - on
page 1, at the head of every profile page and in the document's own
title. That is the legend's internal label: the unified Deaf row is an
affinity bloc spanning every region, so there is no country to name it
and zone-title.js declined it, leaving the label to print.
An affinity-bloc zone has a name of its own even though it has no
country. zone-title.js now reads it from the packet strings, keyed by
bloc (zone_affinity_A017: "Deaf people groups", in all eleven
languages), so another affinity bloc a list adds is named with one
string and no code. With no strings it still declines and the label
stays - it never invents a name. Both print paths now pass the
language's strings, English per key, the same fallback the renderer
applies.
check-zone-title-tier-a covers the unified Deaf zone, which it never
saw (it enumerates clusters.json entries, where Deaf is two older
lists): the translated name in en/es/ar, never internal text, and a
decline without strings. It now tests with the real packet strings,
which carry the multi-country joiner, so a broken one-country guard
would generate a title and be caught.
