// The drawing layout [SPEC 15]: children place their origins on one shared
// datum — symmetric primitives stack concentric with no positioning at all —
// and the view's `scale:` multiplies geometry while text, stroke, and the
// centre-mark chrome stay sheet-space. The smart label is the title, under
// the view.
