// Translating into the phone's language when coinos has no UI in it:
// isolabellart's phone was Italian before coinos spoke Italian, so it ran in
// English and posts were never translated for them. Here a Dutch phone (no
// Dutch UI): an English post is translated into Dutch (the stub answers in
// whatever words); a Dutch 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-phone-lang-test.js
