Worked on improving the robustness of story rendering in the storybookjs/storybook repository, focusing on stability and maintainability rather than new feature development. Addressed a critical issue in the Stories component by ensuring that the StyledHeading element only renders when the title prop is a string, thereby preventing runtime errors caused by non-string titles. This fix enhanced the reliability of story previews and contributed to more consistent rendering in CI pipelines. Utilized front-end development skills with React and TypeScript, applying careful code quality guardrails to the rendering path to reduce future maintenance risks and support ongoing codebase stability.
