+HelloDom — the minimum DOM-mode example. Build with:
+    crafter-build --local --target=wasm32-wasip1
+
+Output lands in bin/HelloDom-wasm32-wasip1-native-native-<hash>/. The
+runtime expects a co-located dom-env.js (provided by Crafter.Graphics
+itself) plus a runtime.js / index.html pair that wires the env into the
+WebAssembly imports — see EnableWasiBrowserRuntime in Crafter.Build.
