Over a two-month period, chltjddbs138@naver.com focused on design asset management and repository hygiene in the chobee81/study3 project. They refreshed branding by adding new Figma and image assets, while systematically removing obsolete files to streamline asset discoverability and reduce maintenance overhead. Their approach emphasized clear, traceable Git commits for each addition and deletion, supporting maintainable workflows. In August, they introduced a binary asset upload process, enabling direct distribution of ZIP files without altering the codebase. The work leveraged Git, Figma, and asset management best practices, resulting in a cleaner repository structure and improved support for reproducible builds and design iteration.
