Major CSS file include problem in the main Yeoman-Angular demo

The celebrated ["Let's scaffold a web app with Yeoman" demo](http://yeoman.io/codelab/index.html) is slowly revealing itself as the anteroom to a world of pain.

After hacking across repeated bower hangups while loading jquery and other 5MB (!!!) of apparently indispensable stuff, I fire the server and retrieve the following, mangled page.


I've been able so far to retrieve [the following CSS file](https://addyosmani.com/critical-path-angular-demo/output/critical/styles/site.css) from a public working example of the same demo and inject it using good old Chrome Developer Tools between two `` tags in the head of the doc.

Page looks now as shown in the codelab pages. But file `styles/site.css` is sorely missing from the app I created following the instructions on the Yeoman site.

Needless to say, as soon as I refresh my page at localhost:9000, I lose the good CSS.

After having to manually installing a plethora of dependencies required by the mission-critical `grunt-cdnify` task (obviously not specified inside its `package.json`), I've managed in some way to run a complete `grunt build` operation. Hacked a few tags in the head of `index.html`, but still the CSS file is not included. Ended up chucking manually the `<style>` tag inside `index.html`, just to be able to get ahead of the CSS issue.

I hope I'll be able to understand how to make that file known to the build mechanism and automatically included in the page.

In the meantime, **please verify and comment on this issue: is or is not the homepage in the app looking as nice as it should? Is the file `styles/site.css` present in the scaffolding built by Yeoman?**
