Hotwire/Turbo + Webpacker/Stimulusjs

I think I'm confused. I love the functionality of Hotwire and experimented a little with it in a fresh app. I don't understand though, if I can also have Stimulusjs running - I have different needs and I'm assuming I would still want Stimulus for all the weird little interactions where someone doesn't save a record but instead needs to preview changes, Hotwire for the actual partial changes that impact the database. Is there a way to do this? All the tutorials seem to be one or the other.

Also - has anyone taken a legacy app and moved things? I'd love to read stories and hear tips and tricks if anyone's got them.
