gregiv_eseleven_ty I made quite a lot of modifications, particularly to CSS/js processing, and I didn't use image processing in favour of an image cdn. I started running the full build including global assets through twelvety but realised it made build times ridiculously long versus seperately.
gregiv_eseleven_ty I suppose because they're processed per-page it scales with number of pages, so I switched to just copying the short code behaviours into gulp tasks.
I'd love to be able to use Nunjucks by default across the entire site as that's what I'm familiar with, but liquid grew on me.
