+ * This declaration allows TypeScript to recognize `.proto` files as modules
+ * that can be imported directly in TypeScript projects, enabling integration
+ * with Protocol Buffers in environments where `.proto` files are parsed or
+ * used as source definitions for generating classes and types.
+ *
+ * @module
+ * @typedef {string} ProtoFile - Represents the imported `.proto` file as a string
