This is the infrastructure layer for building a SwiftUI design system, not just using one. It covers token architecture (raw, semantic, component layers), asset catalog governance, and the Airbnb DLS pattern of style protocols over wrapper views. Mandates @Equatable on every view and keeps everything compatible with the clinic modular MVVM-C boundaries (Feature depends on Domain + DesignSystem only). You'd reach for this when setting up or refactoring the design system package itself, not when just styling a feature screen. It's strict about preventing hardcoded hex values and shadow tokens, with 50 rules across color engineering, typography scales, spacing systems, and theme infrastructure. Works alongside swift-ui-architect for the architecture side and ios-design for actually using the primitives you build here.
