Worked on the sanity-io/sanity repository to enhance the user experience of the Presentation page by implementing a default title fallback. Addressed a UX gap where the page title could be empty or inconsistent by ensuring it defaults to 'Presentation' when no options.title is provided. This change was delivered through a focused update to the presentation rendering path, making the behavior more predictable and aligning with product standards. The solution was implemented using React and TypeScript, emphasizing maintainability and traceability by anchoring the update to a specific commit. No bugs were fixed during this period, with efforts concentrated on this feature.
