- Adding a new string means adding the key to ALL seven locale files in `src/i18n/locales/` (en, es, fr, ja, pt, ru, zh) — not just `en.json`. The English version alone is incomplete work.
- Reuse existing keys (`common.buttons.*`, `common.labels.*`, `createProfile.*`, etc.) before creating new namespaces. Check `en.json` first.
- Strings excluded from this rule: `console.log/warn/error`, dev-only debug labels, internal IDs, CSS class names, type names. If unsure whether a string renders to the user, assume it does and translate it.
+- **Never use `t(key, "fallback")` with a default-value second argument.** The 2-arg form is forbidden — every key must exist in every locale file before the call site lands. Fallbacks mask missing translations: a key missing from `ru.json` will silently render the English fallback to Russian users, so the bug never surfaces in CI or review. Only call `t("namespace.key")`. If a translation is missing for any locale, that's a bug to fix at the JSON, not a hole to paper over at the call site.
+- Empty-string values in non-English locales are also forbidden — a locale either has the right translation or it has the same content as English; never `""`. If a particular language doesn't need a particular phrase (e.g. a suffix that doesn't grammatically apply), refactor the JSX to use a single interpolated key (`t("foo.bar", { name })` with `"...{{name}}..."` in each locale) instead of splitting prefix/suffix.
