the layout graph is maintained, and the shine draws for real

- the interface's layout graph is maintained as anchors change instead of rediscovered from scratch: 1.48 ms per mutated frame becomes 34 µs, and end to end a running cast now costs +0.14 ms where it cost +4.33
- the autocast shine draws its authored population — 1200 particles through the star's own projection, spinning as the model says
- the shine is clipped to its own widget: the model frame installs its rect as the viewport, so nothing it draws leaves the button
