// #357: a plain View tap must work on a COLD tab that never loaded the lazy
// editor runtime (#337). The field failure (dacha, "Гостиная основной свет"):
// a real wall switch whose controls name three passive virtual lamps did
// nothing on tap — _toggleIntent was a stub delegating into the not-yet-loaded
// editor runtime and threw synchronously inside the click handler; opening any
// editor surface "healed" the tab. Every product smoke preloads the runtime
// (launch()), so only a cold-view scenario can see this class of regression.
