Having done a fair amount of LLM webpage generation, it does an okay job, but repeats a lot of "best practices" that are a few years out of date. Specifically around meta tags.

If I were doing this, I would have it do Deep Research or similar on the most minimal, efficient set of tags to include in the `head` tag in late 2025.

It's possible you can get away with a bunch of .md files, but you will need a file to store site-wide metadata and/or YAML "front matter" in the MD to define page-specific variables.
