/**

|
* A single interaction verb, authored as an instanced object on an
|
|
* InteractableComponent (section 16). This is the Blueprint-extensible path:
|
|
* built-in modes are also handled directly by the interaction component, but
|
|
* any custom verb can be added here without C++.
|
|
*
|
|
* CanExecute/Execute must be safe to run on the server. CanExecute may also run
|
|
* on the client for predictive UI, so it must not mutate state.
