Enforce the existing `engine` directives requiring node at `16.x` and npm at `7.x`, failing with a clear error message if a mismatch exists:
```
npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine
npm ERR! engine Not compatible with your version of node/npm: undefined
npm ERR! notsup Not compatible with your version of node/npm: undefined
npm ERR! notsup Required: {"node":"^16.10.0","npm":"^7.24.0"}

```
This change makes the version mismatch exceedingly and immediately clear instead of the developer having to infer from an obscure error much later on in the installation process.
"global-styles" was added to hoist fewer dependencies from packages to the root node_modules and was initially intended to fix some issues with mismatched dependency versions in the Boards unit tests. However, it was found to be causing problems when the same version of dependencies was used across the products.
