Hey thanks, glad you like these projects! Yeah you're right I was only looking at uncompressed size, add in some gzip and actual size through the network is even smaller.
Also glad you like humble, it's one of those side projects I get a lot of enjoyment out of developing and that I can get pretty creative with. You can do some interesting optimizations and modifications when the entire state of a web page is known in advance, and it's fun to look at some of these edge cases.
