This handles custom page transitions and routing animations in WeChat's Skyline rendering engine. You get seven preset routes like bottom sheets and iOS-style modals, or build your own with routeBuilder for things like half-screen popups, scaling transitions, and card-to-detail expansions. The worklet directive requirement is non-negotiable for animation functions, and custom routes only work between consecutive Skyline pages, not WebView. Most useful when you need gesture-driven navigation or want that polished native app feel. The open-container component for card expansions is nice, though you'll spend time wiring up startUserGesture and didPop correctly if you go beyond the presets.
