i just wanted to mention, its not a big detail, but the packager is technically not lossless because it doesn't store the position of the blocks in the html file

well the data is the game and no parts of the game are altered, its like comments. does that count? p2r3 can decide

i think for it to be considered lossless you should be able to convert it to another lossless format and then back and have every single non-metadata bit be the same. My opinion tho

have every single non-metadata bit be the same

what if the image encoder chooses a diffrent compression or something? or alignment weirdities? i think its better to treat lossless as "no useful data is lost"
