MorphSurface class

The Material adapter of the widget layer: renders the visible surface of the nearest MorphTag FROM its declared spec (Material + InkWell with the spec's shape), so the button and the flight can never disagree about the surface. The tap handler receives a context UNDER the tag, which is why showMorph* can omit from: - the morph flies from the surface the finger is already on.

An opinion, not the contract: Material + Ink is one design system's answer, and button accessibility is an app-wide decision - fork this if your app renders surfaces differently. The ENGINE's contract ends at MorphTag.specOf; everything below it is replaceable.
