bambuddy/frontend/scripts/dump-untranslated.mjs

// Dump every (locale, dottedKey, enValue) tuple that the parity check would
// flag as "identical to en, not in allow-list, not auto-allowed". Output is
// JSON, structured so apply-translations.mjs can consume the same shape after
// translations are filled in.
//
// Usage:  node scripts/dump-untranslated.mjs > /tmp/untranslated.json
//
// Logic is imported from check-i18n-parity.mjs (compareLocales) so this stays
// in lockstep with the gate.
