Wonderful! Tested with AfS and disco, including with disco's existing docker setup, and only ran into two instances of this issue:

| throw new Error("Module build failed (from ./node_modules/css-loader/dist/cjs.js):\nError: Can't resolve '../../node_modules/@uppy/progress-bar/dist/style.min.css' in '/web_root/arches-for-science/arches_for_science/media/css'

Doubt that we need to solve that on this PR.

Left some feedback for a little polish.
