Worked on the vscode-classic-themes extension within the zed-industries/extensions repository, delivering version 0.4.1 with targeted improvements to syntax highlighting and theme consistency. Addressed issues with variable and parameter highlighting in both Dark 2026 and Light 2026 themes, and introduced JSON key coloring to enhance readability for developers. Updated the theme source to align with VS Code 1.126.0, reducing visual regressions and ensuring compatibility across versions. Utilized git for version control, managed submodules, and edited toml configuration files. Also resolved a CLA-related commit identity issue, ensuring CI/CD reliability and a clean release process for ongoing extension maintenance.
