Summary

Continuing on from the work in #56 and some of the leftover TODOs from the #74 PR to add more test cases, for the sake of getting the re-org PR first to unblock other work.

Details

Would want to add additional test cases for:

1. Build w/ import in a page with custom front matter
2. Build with all custom templates (index, 404, app template, page template) and custom workspace
3. Build config w/custom workspace and nested pages
4. HTMLElement?
5. Get more coverage on build.js (error handling)

Might just make one big test case, "the works" and put a bunch of custom stuff in there

• HTMLElement header component
• custom app and page template
• custom 404 page
• nested directories

Maybe as part of the work to create a Getting Started section for the website, maybe that would be a good "kitchen sink" use case for this ticket? I was thinking of making a repo that would show the code in its finished form from the Getting Started guide, and this would be a simple way to try and keep it under test within the Greenwood monorepo.
