Canonical Custom Event name emitted by every built-in <sc-*>
element when its user-facing input changes.
The orchestrating <schema-component> listens for this internal
event, applies the resulting structural update to the root value,
and re-emits a public change Custom Event on its own host so
framework consumers observe a single, well-typed boundary event.
