Casper Design System

This is Casper Studios' internal design system skill, and it's surprisingly opinionated in a good way. Built on shadcn/ui and Tailwind v4, it enforces a specific SaaS aesthetic: generous whitespace, restrained purple accent, rounded but not bubbly surfaces. The skill forces you to declare platform (web or mobile) and dark mode support upfront, then pulls from different reference files accordingly. What's smart is the hard rule about reading component and layout references before generating any UI, which should prevent the usual off-brand garbage. It's prescriptive enough to actually maintain consistency across a team's prototypes and internal tools without being a straightjacket.
