Contributions summary:Thúlio primarily focused on adding and refining the functionality of a screenshot service. Their contributions involved implementing a delay feature, allowing users to specify a time delay before a screenshot is taken. They modified the server-side logic (scripts/rasterizer.js and routes/index.js) to incorporate the delay parameter, and made corresponding updates to the form (public/form.html) to allow users to specify delay. There were also reverts of earlier changes.
