Worked on the quarto-dev/quarto-cli repository to address rendering issues related to figure and subfigure captions when using Typst. Focused on improving documentation quality and output consistency, the developer implemented targeted bug fixes that wrapped captions in block elements, ensuring alignment with user expectations and reducing extraneous output from caption numbering. These changes, delivered over two months, enhanced the reliability and readability of rendered documents, particularly for users leveraging Typst and Markdown. The work included updating the changelog for version 1.9, validating improvements through testing and code review, and directly contributed to the stability and release readiness of the CLI.
