How does this import work?

aws-cdk/packages/aws-cdk/lib/util/asset-publishing.ts

Line 3 in e0f863a

import * as cdk_assets from 'cdk-assets';

I've been trying to figure out at which point assets get deployed to the s3 bucket, and write a patch that adds a tag to the resources so I can properly housekeep the contents of the s3 assets bucket with multiple stacks.

What has me puzzled is how it imports 'cdk-assets'.

In the repo, the package.json has a dependency of "cdk-assets": "0.0.0",
In the node_modules of my project it has devDependency of "cdk-assets": "2.14.0",
Nowhere in my project node_modules does cdk-assets exist.
