+**Adding new BridgeJS intrinsics:**
 
 If you add new `@_extern(wasm, module: "bjs")` functions to [`BridgeJSIntrinsics.swift`](Sources/JavaScriptKit/BridgeJSIntrinsics.swift), also add corresponding stub entries to [`Plugins/PackageToJS/Templates/instantiate.js`](Plugins/PackageToJS/Templates/instantiate.js) in the `importObject["bjs"]` object. This allows packages without BridgeJS-generated code to instantiate successfully.
