When do you gain new traits or trait levels?

My players were reading about the difference between level 1, 2, & 3 traits and asked how to “level up” a trait… and I didn’t know. I know some characters can start out with a level-2 trait if their Nature questions give them a trait they already had, and I assume if you get awarded/stuck with a trait you already have, it gains a level, but then that led me to try to look up all the instances where one could gain new traits in general. I know that I’ve come across instances in the rules where characters can gain new traits (like Resources taxed to zero), but was wondering if there is a definitive list of appropriate times, or if traits can be awarded if merited by roleplay at any given time.
