Worked on cross-repository improvements in grafana/k6-DefinitelyTyped and storybookjs/storybook, focusing on API consistency and developer experience. Addressed a type definition issue in Leaflet overlays by updating the getCenter method to return LatLng instead of Point, aligning the API with geographic expectations and updating related tests in TypeScript. Enhanced documentation by renaming Volar references to the official Vue extension and removing deprecated VSCode extension mentions, clarifying onboarding for downstream users. Emphasized maintainability through improved documentation hygiene and testing coverage, using Markdown and TypeScript to ensure both code and guidance reflected current best practices across both repositories.
