• Before #1858: https://deploy-preview-2188--docsydocs.netlify.app/
• As of #1858: https://deploy-preview-1858--docsydocs.netlify.app/

Problems

• Square brackets become escaped in generated output. For example, see https://deploy-preview-1858--docsydocs.netlify.app/blog/2023/bootstrap-5-migration/#grid-row-and-col-style-changes-are-breaking

• Newly generated scripts are at the root level, I would prefer that they be under js:

  $ ls -l userguide/public/*.js

• The newly generated scripts should be minified in production only.
