SSR support

[v1rtl]

Currently trying to use pico with hyperapp on a server results in this:

ReferenceError: document is not defined
    at file:///home/v1rtl/Coding/hyperlight/examples/with-styles/dist/index.mjs?345763421581:21:13

    at async buildSinglePage (file:///home/v1rtl/Coding/hyperlight/packages/hyperlight/dist/hyperlight.js:79:11)

I haven't found anything in the repository about server rendering, so asking it here.

Is there any way to make picostyle work on a server? Maybe with some kind of plugin? Or picostyle is not designed for any server rendering?
