Build me a skill for coding agents that helps them make polished fake product UI for design and motion work.

I want it to help create things like stills, feature cards, cursor demos, and bento grids that look like a real product, all built in React. It should include clear guidance on composition and motion, a simple kit the agent can copy from, some example layouts, and a way to preview or film the result so the agent can check if it looks right. Make it feel practical and ready to use, not like a generic template.

Please set it up so someone can add it with a simple command and then use the skill right away. If you need to look up current docs online, go ahead. Keep the examples and instructions focused on making nice looking UI mockups that are easy for an agent to generate and refine.
