The app's Chinese is Simplified, and so were 39 keys of the packet's zh
block. The other 18 were Traditional - page 1's subtitle, the list
header, the card labels, and the whole prayer wheel and all twelve
prayer points - so a Chinese packet switched script partway through.
The block had been extended by matching the neighbouring line, which
was itself the drift; the missing-map sentence added in 74e5c4b0d
followed that same neighbour and is corrected here too.
Converted with a real converter (zhconv, MediaWiki's tables), not a
hand-picked character list: it converts characters (為 to 为, 禱 to 祷)
and mainland vocabulary (列印 to 打印), and a hand list had found only
17 of the 18 keys. A second pass changes nothing, so the block is
Simplified by the converter's own definition. 祂 is kept. The block
carries no licensed scripture - Mark 5 falls back to English there - so
only prayer prose and labels changed.
check-i18n-parity's zh arm walked the app catalogues and never the
packet's, which is how 18 keys drifted unseen. It now walks the packet
block as well; pointed at the block before this commit it fails with 41
values, and passes after. Its character set remains a floor, as it says.
