+selected controls remain distinguishable by their labels, not color alone. Rounded

 Rendering/uploads occur only for changed content, page, settings, or pointer
 feedback; static frames are reused. The caller may call `draw(Panel)` at 10 ms
 intervals. Tracking transforms do not require repainting the canvas.
