- Add Draw(gtx, r *Renderer) to Element interface - Add Container type that implements Element and holds []Element children - Leaf types (Label, Icon, Button) implement Draw themselves - Single recursive drawElement function in Renderer — no switch/case - Remove StatusBar/BottomBar — replaced by Container - Remove shaper.go — no longer needed with Gio material labels - Simplify main.go — scale via ScaleProvider interface - 5 files changed, shaper.go deleted
