Worked on the zed-industries/zed repository to deliver a major upgrade to Mermaid diagram rendering, focusing on improving SVG rendering reliability and performance in Markdown previews. Migrated generic SVG cleanup responsibilities from the core crate into the merman renderer, enabling a raster-safe SVG pipeline and enhancing maintainability. Addressed fallback overlay handling by ensuring correct identification and styling, which preserved host CSS classes and improved UI consistency. Validated changes through automated testing and code quality checks using Rust tooling. Collaborated on release notes and UI/UX checklist updates, emphasizing business value and a smoother developer experience for documentation and preview workflows.
