Worked on stabilizing the UI skeleton and sign handling for the Sojourn-Iskhod repository, focusing on backend development and code refactoring using DM. Addressed UI robustness by implementing HTML skeleton standardization and refactoring the show_browser function to utilize the new structure. Unified sign usage by replacing custom SIGN macros with the built-in sign function, while adding conditional definitions to maintain compatibility with older DM versions. This approach resolved 516 errors, enhancing UI stability and maintainability across versions. The work demonstrated a methodical approach to improving cross-version compatibility and user experience, with a strong emphasis on backend reliability and game development practices.
