CLEAN UP DUTY - minimize extraneous/unused lines of code or entire files

[mathcodes]

We have decided to go with TailwindCSS for our UI framework, so there will be lots of css/scss that will need to be refactored using TailwindCSS's syntax (another issue).

This issue is solely for eliminating unused code. Please be sure when you remove anything, you check that all the previous functionality of the app remains.

Little by little. Many PRs are fine with me.
