Liquid Glass

This one's for building SwiftUI apps that actually look native to macOS and iOS. It enforces Apple's Liquid Glass design system with the core rule that glass effects belong on navigation and controls only, never on content itself. You get patterns for cards, rows, badges, and buttons with proper materials and the new glassEffect API, plus strict adherence to HIG spacing (8pt grid), typography (11pt minimum), and the 44pt hit target rule. The three-layer model and continuous corner radius requirements are baked in. If you're tired of SwiftUI apps that feel like web views wrapped in a window frame, this keeps you honest with Apple's actual design language.
