+> **Memory management:** In all modern browsers (and wasm-bindgen ≥ 0.2.91), WASM memory is freed automatically via the TC39 weak references proposal when the JS object goes out of scope.
+> 
+> In practice, you often don't need to think about this. For deterministic cleanup or environments without weak reference support (older browsers, some Node.js setups), use `using` (TypeScript 5.2+ / ES2026) or call `.free()` manually. 
+> 
+> Never call `.free()` on a `using`-managed instance otherwise it will double-free.
