Universal retained-node capabilities shared by every visual node and control.

Rust controls use composition rather than FUI-AS class inheritance, but this trait preserves the common retained identity, state, semantics, focus, routed-input, gesture, geometry, and child-inspection contract. Layout and appearance are exposed separately through the cohesive surface traits.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
