// This val implements a simple comments system using Val Town's Blob storage for persistence.
// It handles GET requests to retrieve comments and POST requests to add new comments.
// The approach uses the built-in Request and Response objects for handling HTTP requests.
// Tradeoffs: This is a basic implementation without user authentication or spam prevention.
