Covered first pass through options and some of plugins
Update organization of embed plugins, remove iframe code snippets and examples
Update Turnstile embed options
Update post roll embed options, remove postroll params doc
Update social bar params, remove old params doc
Update captions params, remove old doc
Update styles across docs, specifically technical docs

Reduce line-height across doc, tighten up some padding for code blocks and
such.

Re-named 'syntax' partial to 'technical docs', because it made more sense to
look there for styles.
