WebContainers and Native Node.js Module Interoperability

StackBlitz WebContainers implement a Node.js runtime via WebAssembly to enable browser-based development. While the environment supports standard JavaScript-based packages, the virtualized POSIX-like file system introduces constraints when integrating native Node.js modules written in C++.

The current architecture requires native modules to be provided as pre-compiled WASM binaries to function within the browser sandbox. This creates a compatibility gap for projects relying on third-party dependencies that distribute only source code for native compilation during npm install.

What is the documented mechanism for importing external pre-compiled WASM binaries into a WebContainer project to replace native C++ modules? Does the environment support a custom mapping configuration to redirect native module loads to these binaries?
