So I've played since PF1, and from The Old Times, I know the importance of the Fundamental Runes enchantment (or what used to be The Big 6, which I don't fully remember all of anymore), and I understand that the balance of PF2 assumes that fundamental runes are expected at certain levels, based on the what level the runes are.

However, if I was brand new and wasn't using Reddit/other communities, is there anything in the books that specifically tells you, either player-facing or GM-facing, that these are things I should be trying to obtain/give to my players? I realize that the word "fundamental" is there, but I think there should be a larger highlight on the fundamental runes to let newer players know "hey the game assumes you have these at these points, so they should be obtained/available/given at these points"
