 * inside the `react-server-loader` dependency, under its `vendor/` dir. We
 * resolve it through the package so it works whether rsl is a real install,
 * hoisted, or symlinked (dev). `react-server-loader` exposes `./package.json`
 * in its exports map, so this resolves under any resolution condition.
