Contributions summary:Sean primarily contributed to the Chromeless project by adding new APIs and functionality. They implemented features to set and get HTML content, including adding a new `setHtml()` method. Moreover, they added the `getHtml()` and `pdf()` APIs, which involved interactions with the Chrome DevTools Protocol and integrating with AWS S3 for PDF storage. They also refactored and updated existing code, renaming methods and allowing for options to be passed into the `pdf()` API.
