It is largely written by iteration with an LLM! No need to speculate or analyze em dashes :-)

The emoji idea was mine. I like it :-) unfortunately it doesn't work in places like HN that strip out emoji. So I had to make a base64 encoding option.

The goal was to create an effective encryption key for the url hash (so it doesn't get sent to the server). And encoding skin tone with human emojis allows a super dense bit/visual character encoding that ALSO is a cute reference to the humans I'm trying to center with this project!
