Tool called "heap snapshots" that will help us figure out if the dom tree is detached but referenced in the script...
-possible thing for why nodes are going up and listeners: html is getting detached that has listeners associated with it, and so it's just growing over time?
Not clear whether it's a Phaser thing, or a StoryAssembler thing, or a combo-of-both thing...but it does seem to spike reliably every second (refreshNarrative()??) but it also slowly grows over time in the intro sequence...so...?
