Goes like this:

* There are no decorators in Web Components.

Instead:

* Whenever a CSS variable (http://dev.w3.org/csswg/css-variables/) changes, it fires a simple event (non-bubbling, non-cancellable).
* There's a CSS-based method for building extra rendering blocks of around DOM elements (http://lists.w3.org/Archives/Public/www-style/2012Jan/0202.html).

The latter allows us to avoid creating a markup-based vehicle to generate rendering blocks. The former allow us to send signals down to custom elements whenever rule starts/stops matching.

I'm confused by the simple event.  What does it fire on?

How do you envision this helping?

You're confused?! Imagine me re-reading what I wrote. I blame it on a bad batch of crack. I'll rewrite this better tomorrow.
