[DaveSkender]

Caution

Experiment only (do not merge)

done when

• Add base, remove Jekyll site (experimental, broken)
• Implement DocFX to auto-generate API
• add custom filter
• Fix many, many basic things
• YAML for redirects, renames from old site (see github.io repo example)
• Add back metas, SEO, and web vitals configs
• Handle production vs preview site (e.g. exclude indexing, though may be already in CF headers)
• Update build/deploy for doc site

Some perspective views. Seems a bit clunky with the auto-generated API reference, over-exposing inheritance; and get's a bit hung up from our recursive chaining methods. With that said, it'll do markdown page generation just fine. We'll explore some others.
