And/or multi-image sequences and the like too, I guess. I tried to search to see if this has been asked before, but I'm can't think of proper search terms and I didn't find anything with what I did search.
My question is, when a comic or image series takes place in a preexisting setting or universe, like pokémon_mystery_dungeon or how_to_train_your_dragon, would it be correct to apply the tag to all pages of the comic that take place in that setting? Or should they only be applied to specific pages that have something clearly identifiable to the setting? Like how this page clearly shows a location belonging to Pokemon Mystery Dungeon (Sharpedo Bluff), while the very next page doesn't (unless you count the vague background details as being a particular dungeon in one of the games).
I know general tags are on an image-by-image basis (characters can regularly change between male/female/intersex/ambiguous depending on what you can see on any given page), but I don't know if the same applies to tags that indicate a particular setting given that it already relies on a level of external knowledge/lore to identify (which can itself sometimes be ambiguous, like this which has pokemon exploring a cave/dungeon reminiscent of PMD, but hardly a PMD-exclusive trait).
