Storage Layout Element
@Serializable
A holding area showing the entities currently in a named delay (8K.4). suspensionName matches a delay's suspensionName; when a delay is unnamed the renderer keys it by the entity's type name (a stable, shared default), so a storage can bind to either. position anchors the element (entry of the belt / corner of the box); style chooses the arrangement. Beyond maxShown members the element degrades to a count badge + capacity gauge (driven by capacity; 0 = unbounded).
