Sysvale/cuida — reverse-engineered prompt

I want a reusable Vue design system called Cuida that people can install in their app and start using right away. It should work as a plugin you register in the main app file, load a bundled stylesheet, and expose shared helper utilities so they can be injected across the app. Include a small but solid set of polished UI components in the same style system, with at least a clear example like a Badge component, and make sure the components feel consistent and easy to use.

Please also set up a nice local documentation site where I can browse the components, see examples, and check the available design tokens and styles. I want the visual tokens available in SCSS too, so teams can import them into their own styles. Add tests so the components and utils are covered, and make sure the project runs locally with the normal dev commands, with Docker support if it is already part of the repo. If anything is unclear, look up the current docs online and keep the result close to the existing Cuida branding.
