The packet and card-deck title named the selection's zones and countries only.
Since India's states bring people, a selection of states alone had no names, and
reduce() threw "Reduce of empty array with no initial value" at the reader.
selectionTitleNames (data/selection-export.js, pure) adds the states and union
territories that brought people. A province with no table is not named. A
selection that brought nobody (Mizoram or Nagaland alone) gives the keyed
"no people groups to print" instead.
check:batch-selection-export arm A6 tests it on the real served table: Gujarāt
alone is titled "Gujarāt", a state + a country names both, a province beside it is
not named, and Mizoram alone reads the keyed text. Its negative control shows the
old naming is empty and reduce() throws. The call site is pinned in arm C. Four
mutants each fail.
The wall intro writes its total in the digits the translated sentence already uses
(countInSentence): ar shows ٢٬١٠٧ beside its own ٢٧ and ٩:١٤, while CLDR's bare
'ar' would have formatted 2,107. Locales whose sentence uses Western digits are
unchanged. The fetching status goes through the same helper.
A people-group load that fails without a catalogue key (the 30 s abort, a dropped
network) now reads as the stall text, "still loading, try again in a moment",
instead of the browser's own English ("signal is aborted without reason"). Keyed
errors keep their own text, and the failed load leaves the cache, so the next Copy
fetches again.
check:upg-count arm E renders the intro through each locale's catalogue and
requires one digit system, with a negative control on the old ar render. Its
separator scan now also reads fr U+202F and ru U+00A0. check:batch-selection-export
arm A5 aborts a real fetch and refuses a real connection; both must read as the
stall text, and the old path must still show the raw message.
