shorthands are nice when prototyping, but deriving them from the browser isn't really safe long term

I am considering removing them from a new version of zaftig and tightening up the API a bit.

Plan would be to add them back as a helper plugin in a static safe way.

I say it isn't safe because a change to the browser could result in styles breaking, because shorthands are derived from the browser APIs based on their order.
