// The `process-compose` bin of @tldraw/scripts: self-provisioning process-compose.
//
// process-compose has no npm package, so installing it is normally a separate brew/curl step. Exposing
// it as a workspace bin lets `yarn dev-app` (and anything else) call `process-compose` like any other
// tool; on first use this downloads the pinned binary into node_modules/.cache, then execs it. Caching
// it there (rather than a top-level dir) treats it like any bundled-binary dep: nuking node_modules
// re-fetches it. Only people who actually run the dotcom stack pay the one-time download (Yarn doesn't
// run a workspace's postinstall, so the fetch is lazy rather than eager).
