Thanks for the clarification. The key part that I was missing was the FFI. I'd encountered projects like this in the past with either no FFI or no documentation for the FFI and I couldn't figure out how to talk to the DOM. I'm more than happy to drop down to javascript for those parts, but I wasn't sure that I'd have the option.
