I managed to answer part of my own question: there is indeed a “site meta” tag, which I had failed to find by following the “tags” link accessible via the hamburger menu at top left but which is found by searching for “meta”. I failed to find it via the “tags” link not because it wasn’t there but because it looked (to me) like a heading rather than an actual tag. Duh.
Presumably the absence of “meta” from the hamburger menu is because we are no longer supposed to find things via menus but instead by using the tag system. It is not obvious to me that this is an improvement.
