During February 2026, work centered on enhancing the Handy repository by implementing comprehensive Korean localization and translation support. This involved updating language metadata and creating a detailed Korean translation file to improve accessibility for Korean-speaking users. The approach focused on establishing a scalable internationalization framework, using metadata-driven translations and structured translation file management to prepare the application for future multilingual releases. Integration was validated across core front end components to ensure seamless user experience. The development process utilized TypeScript and JSON, with an emphasis on front end development, i18n, and localization, laying a solid foundation for ongoing accessibility improvements.
