I don't have a clear solution, but it looks like the root cause is that in the absence of an author, the title is moved to the beginning position *and* the date consists only of the year.
Adding a full date to the example from the initial post the result is
“A DSL That Is Concise and Fun.” 2021. November 23, 2021.
... and adding an author as well results in
Scalding. 2021. “A DSL That Is Concise and Fun.” November 23, 2021.
Now, at least the latter results looks perfectly normal, so I don't think this is a CSL style issue per se.
I guess in principle, the mechanism that moves the title could be made to also check whether this leaves years or a date and a year side by side.
On the other hand, I'm not sure this is really worthwhile, since in practice you should probably always include an organization field in the biblatex data, which in turn ensures that the year and full date are separate, even if there is no author and the title is moved.
