You can use the approach I use in [GitHub - merefield/discourse-tc-tag-cloud: A Discourse Theme Component that displays a tag cloud above the tag lists on the tags page · GitHub](https://github.com/merefield/discourse-tc-tag-cloud)

Note the assets are registered here:

And sit in the assets folder.
