Where do Tool Proficiencies come from now?

I don't have a copy of the new PHB yet since my current campaign is staying with the old rules. For a potential mini campaign to test the 2024 rules, I want to play a crafter of some sort.

However, I am a bit confused on the sources of Tool Proficiency.

What are all the different ways to get Tool Proficiency in 2024? I only know of Backgrounds, but it seems that using an older background (like Haunted one) doesn't offer tool proficiency according to the free rules I found online.
