Contributions summary:Salem primarily worked on refactoring and porting various JavaScript and related UI components into the Node.js-based Pattern Lab project. Their contributions focused on migrating core functionality, including URL handling, post-messaging, and data saving, from an older codebase. They also replaced the jwerty library with the more comparable Mousetrap library for handling keyboard shortcuts and ensured the UI components such as the Modal and Viewport were responsive and properly sized, along with minor UI style adjustments.
