Hi Scott,
Huge thanks for making use of this forum for your question!! (I hope others will pipe in with questions as they have them).
We are very interested in supporting publications like yours, but will likely need to experiment a bit with you to make it happen. If you are open to experimenting with us, we’d be happy to see what is possible.
At the moment, our developers are saying that the best way to do this would be to publish using ePub ingestion. If an ePub has MathML in it, it should render as-is in the browser. The problem is that at the moment, only FireFox and Safari support MathML natively ( https://caniuse.com/#feat=mathml ), which means that (according to our developer), “you want a polyfill in place to support older browsers.”
It looks like with some experimentation we should be able to help you, so please let us know whether you are interested. And thanks for using Manifold!!
Best,
Matt
