+ * This module provides a way to install SWC bindings without eagerly loading the entire swc/index module.
+ *
+ * The swc/index module can transitively load other modules (like webpack-config) that import React,
+ * and React's entry point checks process.env.NODE_ENV at require time to decide whether to load
+ * the development or production bundle. By deferring the require of swc/index until this function
+ * is called, we ensure NODE_ENV is set before React is loaded.
