YlanAllouche/color-whirl ? reverse-engineered prompt

Build me a small app that lets people generate wallpaper images from simple recipes.

I want a web editor where I can tweak a wallpaper, see the result, and share it with a link that keeps the current settings in the URL. I also want the same editor to be reusable as a component in another app, and a CLI so I can generate wallpapers from a config file or a pasted JSON recipe.

The main flow should be easy, I should be able to choose a recipe, set the size, pick colors, and export a PNG. It should support loading config from a file, inline JSON, or a shareable encoded state, since I may want to use the same recipe in the browser and from the command line. If you need to check current docs for SvelteKit or packaging details, go ahead and look them up online.
