Developed and delivered the blk theme for the zed-industries/extensions repository, expanding user customization options through a modular theming system. This work involved creating a dedicated Git submodule and updating TOML configuration files to support scalable theme integration. By focusing on front end and theme development, the implementation improved UI flexibility and visual consistency across themes, aligning with broader product strategy. The approach established a foundation for future extensibility, enabling easier addition of new themes without major architectural changes. No bugs were reported or fixed during this period, reflecting a focused effort on feature delivery and maintainable, modular code structure.
