Web: one counted(n, one, other) helper. The sync screen's three "(s)"
messages (attachments that didn't download, changes refused, files that
didn't upload) now say "1 file" / "2 files". The six hand-written ternaries
(SyncView x2, ImportNotes, GroupList, ShareDialog, LabelsModal) use it too.
Android: tags_count was two strings chosen in code, and is now <plurals>.
The delete confirmation read "It is on 1 notes … removed from all of them"
and now has a one form of its own.
Operator decision on #5371, 2026-10-08.
