Adding initial impressions:

The first-blush API for defining a web component looks pretty nice and simple. Probably won't have the best performance in the world but that's fine for situations where I just want to sprinkle some interactivity to a server rendered or static site.

The store looks nice in some ways, but the actions/mutations language looks very boilerplatey and convoluted. I feel like I'd want something much simpler like jotai or zustand.

The event bus... seems on first blush like it'd be awkward to mix multiple event buses into a single component?
