Ask HN: Enterprise-focused CSS frameworks or component libraries?

I'm curious what everyone is using as far as internal-facing CSS frameworks?

I gravitate towards Bootstrap for most of my projects as it's so darn easy to whip up something that looks decent in a short amount of time, but on the flipside I'm starting to feel that if I have to look at another Bootstrap site my eyes are going to start bleeding.

I found, and like, Project Clarity[0] from VMWare, however it's mostly focused on an Angular use-case whereas I would like something more JS framework-agnostic.
