I just VTC'd a recommendation question using custom text (the only other option was "price shopping" and it wasn't exactly that). The OP replied that they had checked the help pages and didn't see that asking for recommendations were off-topic here. I checked the help pages myself, and the On Topic page is empty!
The only site-specific line is:
The Great Outdoors Stack Exchange is for people who love outdoor activities, excursions, and outdoorsmanship.
It does link to the Don't Ask page, but that just contains more generic boilerplate about not asking subjective questions.
This site has been around for a while! We should have a custom summary of what questions are considered on or off topic here.
