You are an experienced frontend engineer and creative technologist. Your task is to design and implement a fully client-side web application that generates a dynamic calendar wallpaper image. The project must be suitable for hosting on GitHub Pages (static hosting only, no backend, no server-side code). The application must rely исключительно on HTML, CSS, and JavaScript running in the browser.
