ktye.github.io is on github. for local testing i use "go run serve.go", see https://github.com/ktye/ktye.github.io/blob/master/serve.go But my index.html has the wasm module embedded as a string and can load from a file url.
if you do "make k.wasm" and serve the project root with some web server, and request /k.html from a browser, it should display a usable k repl (no banners and prompts yet, so it's all black initially)
