The classifier matched "line" as a bare word, so "LINE MAN: Food Delivery & more"
(Thailand) and "Malé Taxi Line" (Maldives) each ranked as the country's top messaging
app, ahead of WhatsApp. LINE now matches only as the whole name or before a colon.
The classifier moves to app-kind.mjs so the fetcher and the table builder share it,
and the builder re-derives each kind from the app name, so a cached fetch made under
an older rule cannot carry its answer forward. The headline count is computed from
the rows instead of typed: WhatsApp (Messenger or Business) is top in 73 countries.
