Fails on Radium-style media queries

[cryptoquick]

First of all, awesome plugin, it's a lifesaver, I was able to refactor away most of my FS calls on backend components, and remove inlined CSS blocks from my frontend components. I'm not using Webpack, but a static site generator of my own devising.

Unfortunately, code like this will fail in the parser, and I'm unsure why:

.bg {
    text-align: center;

    @media (min-width: 800px) {
        height: 580px;
    }
}

I know that's not proper CSS syntax, but it's the kind of syntax that Radium / React-Styling want to describe media queries.

Here's the error in full:
