Add LuaLaTeX and you're cookin' with gas. For real would be fantastic if we could get more or less the full LaTeX ecosystem readily and rapidly available online and in a huge variety of desktop applications.
I’m really glad the main AI chatbot apps and sites support latex rendering. I tuned my system prompts to get the bots to explain their high level reasoning in equations for me to read if they think it will convey more nuance or dimensionality than casting down to English.
I'm looking forward to run Lua inside Latex inside Javascript inside Firefox inside my Android ART virtual machine.
