Hello again!
At this point, I can't guarantee HTML5 export. It will depend on a few factors down the line. My primary focus is to make ACSG as robust as possible within a single environment. And honestly, even Windows itself, with versions 11 and 12, is making cross-platform compatibility a bit more... interesting, let's say. :) However, it is a possibility I'm considering for the future, but I can't make any promises right now.
Thanks again, and stick around! ;)
