/**
 * Demonstration of using the SitemapsConstruct and SitemapFreshenerConstruct
 *
 * ⚠️ CAUTION: This uses the "Easy Button" approach where the construct will create and own
 * the DynamoDB Table and S3 Bucket.  This approach is not a CDK best practice.
 *
 * The CDK best practice is to put "durable" assets like DynamoDB Tables and S3 Buckets
 * in a separate stack that is deployed once and managed separately from the application stack.
 * This ensures that data is preserved if the application stack has an accidental resource
 * id change that would cause the stateful resources to be deleted and recreated.
