Worked on refining localization for the mhsanaei/3x-ui repository, focusing on improving the Russian login page experience. Updated the Russian translation for the login page title from 'Приветствие!' to 'Добро пожаловать!' to better align with the English 'Welcome' and ensure consistent user interface language. This change was implemented by editing the translate.ru_RU.toml translation resource, demonstrating attention to internationalization best practices and careful version control. The update enhanced onboarding for Russian-speaking users by reducing potential confusion in the UI. Utilized TOML for translation management and applied internationalization skills to support a more cohesive multilingual user experience.
