TemporaryLooker22/Check-UI-Clean-Roblox ? reverse-engineered prompt

Build me a Roblox UI kit for simulator style games that looks like the examples in this repo.

I want a clean, polished design system I can drop into Roblox Studio, with reusable modules for themes, components, icons, and client side interactions. It should make it easy to create the five standard menus people use in these games, Shop, Codes, Rebirth, Settings, and Daily Rewards, and they should all feel consistent, colorful, and “premium” instead of flat or generic. Make the buttons feel 3D, the headers bold, and the layouts responsive so they work well on phone, tablet, and PC.

Please include ready to use example screens for each menu, plus a combined demo screen so I can see everything working together. If you need to check current Roblox UI behavior or best practices, look up current docs online. Keep it practical, clean, and easy to copy into a game project.
