Wire dependency-cruiser into a TypeScript repo so each package is a deep module, with implementation hidden in subfolders and reachable only through its entry-point files. User-invoked. Make every package in this repo a deep module: a lot of behaviour behind a small interface. A package's public surface is its entry points (the files at the package root), and everything in its subfolders is hidden.
