    Interface StateChangedPayload<T>

    Payload of state:changed with value and previousValue typed for a key whose values the page knows; without a type argument they are unknown. FBEventPayloadMap['state:changed'] types them as JsonValue, which is what the host sends.

    interface StateChangedPayload<T = unknown> {
        expiresAt?: number;
        key: string;
        previousValue: T | null;
        sourceWindowId: string;
        value: T;
    }
