okay so like, hear me out here

this commit isnt QUITE done but its in a working state, and i just had
the scariest vision of accidentally discarding all my work via git
mishap, yknow? even though im not doing anything funky with git! so yall
get this commit early and its goin on line but im not pushing it to the
site til its done. no spoilering yourself (even though ive already
posted most of the cool things in the discord) <3
