no issue
https://github.com/TryGhost/Casper/pull/403 added optimisations for reducing size of zip files but unfortunately it also stripped out `assets/css` which means that it's no longer possible to download the theme from the admin panel and use it for development.
- remove `assets/css` from the ignored files in the `zip` task
no issue
- Optimised the `gulp zip` task, so the zip file doesn't include the `assets/css` (`built` folder is used for CSS) and the `dist` folder (is used to output the zip file)
