check:approx-pin-note server-renders ApproxPinNote in Node, and it crashed: with no locale argument
and no runtime locale, formatList fell through to detectLocale(), which reads `document`. The page
lookup is now a guarded last resort. ApproxPinNote also passes its sentence's own locale (the
host's vue-i18n when installed, else '' so the runtime/page chain applies), so a host with its own
i18n can never get an Arabic sentence with a list in another language.
The gate now expects the new English ("Koraga and Maila", the list grammar this change exists for)
and adds the Arabic case: two names joined with و, never an English comma inside Arabic prose.
Poisoned by putting join(', ') back, both of those cases fail; restored, it passes.
