- Add ui.Dp and ui.Px as distinct named types - Logic layer works exclusively in Dp (positions, sizes, regions) - Renderer converts Dp→Px at Gio interop boundaries - Capture gtx.Constraints once at start of Draw() for consistent positioning - main.go converts app.ConfigEvent pixels to Dp before passing to logic layer - Update documentation with new coordinate system architecture
