+// @env NYASH_PLUGIN_ONLY=1
+// Notes:
+// - PyRuntimeBox.eval() with zero args reads NYASH_PY_EVAL_CODE on the host side.
+// - Avoids StringBox and println to minimize unsupported JIT lowerings.
+// - Build AOT:
+//     bash tools/build_python_aot.sh examples/aot_py_eval_env_min.hako -o app
+// - Run:
+//     NYASH_PY_EVAL_CODE="(__import__('math').sqrt)(9)" ./app
