I made a change today that seemed right, but something about it was nagging at the back of my head. So before I deployed it, I asked our robot overlords… It correctly pointed out that I had forgotten the old code worked that way for a reason! A snippet from its analysis:

Original behavior likely intentional: archive_site previously only ran prepare_plugins(…, full_themes: false) so “small” plugins could contribute assets/includes, but it avoided full theme overrides and didn’t layer the user’s theme on top of “archive”.
