// Translating into the phone's language: isolabellart's phone is Italian,
// coinos has no Italian UI (so it ran in English), and posts were never
// translated for them — the target was the app's language, and the guess
// didn't know Italian. Now an English post is translated into Italian on an
// Italian phone; an Italian one is left alone; Settings → Translation names
// the target and takes a DeepL key, which then rides with each request.
// The registrar's /translate is stubbed (window.fetch shim).
// Run: bun tools/translate-italian-test.js
