// Release gate: every tree Node runs from Resources/, outside
// app.asar, must declare its own module format. Without that, a package.json
// above the install folder decides how its .js files are read (npm 11's
// `npm init -y` writes "type": "commonjs"), and every `import` becomes a
// SyntaxError at startup.
