Adding RTL locales is a follow-up ADR — we want the i18n + plumbing to land first, then content. +- **No Monaco localized messages.** Monaco ships English-only; we leave + overrides out of scope. +- **No locale switcher in the UI.** The user picks locale via the OS settings, + which `detectLocale()` reads from `navigator.language`.
