+Treat each workspace or config root independently. A monorepo may need multiple Rstack config files when commands run from different package directories; validate config discovery from each directory.
 
 Use one of the default names: `rstack.config.ts`, `.js`, `.mts`, or `.mjs`.

+The factory also provides Rslint's built-in globals catalog, so an external `globals` import is unnecessary:

 ## Script Pattern
 
 If a script also runs Prettier, migrate its formatting command as described in [prettier.md](prettier.md).
