for anyone interested, with a little hackery i was able to inline raw css: https://gist.github.com/eyelidlessness/a2993d7c48c17e5fc9a55012b702e4dc

imo it'd be nice if "top level" were specified by a protocol for exactly this kind of extension, i'd like to offer a simple patch for that purpose (rather than continuing to wrap the private var) but want to get feedback about it before i do
