I18n UI
Design and implement multilingual, internationalized frontend UI components and applications. Use this skill whenever the user mentions: multilanguage, i18n, internationalization, localization, l10n, multiple languages, RTL support, Arabic/Hebrew layout, translation keys, locale switching, language detection, or building any UI that needs to work in more than one language. Also trigger when the user asks to "add language support", "support Vietnamese/Japanese/Arabic", "make the UI multilingual", or shows a design that will be used globally. This skill covers architecture decisions, code patterns, component structure, and common pitfalls for React, Vue, plain HTML/JS, and framework-agnostic scenarios.
