The main thing is that I was getting "RequireNotFound" warnings for
`require 'rails_helper'`, because the LSP seems unaware of how RSpec
offers `spec/` as a root for requires.
I think the `require_relative` is clearer anyway, I'm decently
satisfied with it. And if I decide it's too much ugly, we can try
something else in the Solargraph config or something sometime!
I only now thought through that I can scrape these instead of enter
them manually, similar to how we did our Rainbow Pool scraper… hooray!
I'm actually writing tests for stuff too, wowie!
