Thanks!

Yes, Marp is interesting. It has a lot of capabilities and extensions. When I’m creating a slide deck, I usually go straight to PowerPoint so that I can do animation. But if I needed to do a super-quick deck in a hurry, I’d be tempted to use Remark.js, since it’s totally self-contained, or one of the formats that Pandoc can output, since Pandoc has some useful extensions.
