The userbar style is copied from Daniel15's Userbar Generator. The font used is Visitor. I used dewinfont from here to convert the .FON into raw bitmaps for embedding inside the program.
the JS frontend (in userbar.html) needs coloris.min.js and coloris.min.css from here, and libuserbar.js and libuserbar_bg.wasm built using wasm-pack (by running wasm-pack build --target web in the libuserbar directory).
