Replace Bower with npm or other tools

`Bower` is going to be deprecated. `bower install` gives the following message:
```
npm WARN deprecated bower@1.8.4: We don't recommend using Bower for new projects.
Please consider Yarn and Webpack or Parcel. You can read how to migrate legacy project here:
https://bower.io/blog/2017/how-to-migrate-away-from-bower/
/usr/local/bin/bower -> /usr/local/lib/node_modules/bower/bin/bower
```

Start by locating the project's Bower configuration and current `bower install` workflow, then read the linked Bower migration guide and compare the replacement options named in the issue. Done means the project no longer depends on Bower and its dependency-install workflow is documented and verified, but the issue does not identify a target tool or files.
