Worked on the onekey-sec/unblob repository to enhance both the development environment and documentation systems. Improved the local setup by updating the gitignore to exclude generated files and adding missing Nix dependencies, streamlining onboarding for new contributors. Focused on MkDocs-based documentation, reorganizing format guides, extending snippet support, enabling HTML in Markdown, and refining table styling with CSS. Addressed a documentation rendering bug by adjusting heading hyphen spacing to resolve MkDocs compatibility issues and fixing broken links. Leveraged skills in Python, CSS, and build systems to deliver maintainable improvements that reduced support overhead and enabled faster iteration on new features.
