CastRefusedEvent
constCastRefusedEvent:EventHandle<CastRefusedRecord,Reliable,Entity>
On the caster each time the room refuses her cast, as it starts or
once it waited for her to walk into range: why, and, for
Refusal.NoResource, the resource she had too little of, which the
page shows in one line. Its cause is the cast command, so her page
alone reads it as the refusal of her own cast.
