I found this to be key...

The goal of this entire matter is such that only the current ‘articles’ will be available to the website’s audience at any time – no saved, archived, or otherwise stored content provided by the ‘external author individuals’ will be provided on this website. Additionally, the website’s owner will also produce a very limited amount of content (e.g. approximately four [4] articles each year).
As you say, "No website feature other than those described are desired." The advice is a straight up web site, no CMS.

Static websites may well be on their way out -- but poor design of CMS systems ensures a slow march. Improving usability and functionality does show promise for the future.
