Just did a "mini" build version of Cardinal on the web, see https://minicardinal.kx.studio/
Only contains core and fundamental modules, extras like carla/ildaeil are also not in there.
The intention is to have something that is quick to load, so I can more easily show it to people, and also place it in a "software portfolio" I am working on.
The mini version assets have a combined 15Mb size. It is small enough that Firefox is happy to cache the page, so that's nice :)
Feel free to use and share!
