// rnx's binding of the shared runtime-delivery machinery.
//
// the machinery itself (hosted manifest, sha256-verified tarballs, channels,
// channel resolution, and auto-update) lives in @contrast/runtime-delivery and
// knows nothing about rnx. this file supplies rnx's identity, public env
// overrides, and the contrast.dev/runtimes hosting layout.
//
// @contrast/runtime-delivery is an internal workspace package that is never
// published, so both the CLI bundle and dist-lib inline it (see the `alias`
// entry in scripts/build-cli.ts). pack-smoke fails the build if it ever leaks
// out as a bare require.
