How's that possible?  Info files are plain-text files with some
special-purpose control sequences.  Plain-text means it's just a
sequence of Unicode codepoints.  How can a plain-text file express
layout produced by LaTeX?

It's not really practical in HTML, either; that's the entire point of MathJax
(a "_javascript_ display engine" library that recreates a subset of TeX for 
CSS + SVG or web-fonts). MathJax is used by systems like AsciiMath for
this purpose, but is anything but lightweight, and the usual expectation is
that you're either calling out to a web service, or running node locally.

I hope that helps,
