A questions about Uku theme

Hi :) I have a few questions about Uku theme.

1. Does it have any repository (Git)? I Want to see the source codes of CSS and JS files, not minifed versions.

2. Or you writing all the content of style.css simply by hands? I’ve noticed strange things here. For example:

@media screen and (min-width: 112.500em)

Thank you for the great and awesome themes!
