To hoist the comment—this is an "experimental dev-only package" right?
The StrictMode syntax mostly looks good, it's a great start. I think the only thing I'd like is that const padding = '8px'; local reusability.
Issues:
- The hashes are wrong!
- Could use validation of sorting (it's more important than it may seem)
- What about sorting? I'm not 100% certain how it works.

Not sure why we need a peer dep here actually, but ^18.2.0 to match Atlassian…unless Compiled has this peer dep elsewhere then just match it.

I thought I defaulted this to ["@compiled/react", "@atlaskit/css"] elsewhere, could you check and match?

Is there a way for a friendlier message, eg. I saw the "…not supported in Strict Mode…" before?

This might actually require refactor in a few places, but sparingly, that's fine.

This will definitely break in a few places, this is a "supported value" by default, it'd be ideal if at a minimum, this was supportable, because it's the only option (barring token(…) babel plugin type effort) for value reuse—local reuse is fairly necessary.

This test doesn't particularly do what it says ti? Eg. the hashes are wrong.
Be lovely if it could be 100% hooked up, then we could just have a huge css({ … }) edge-case call and compare it 1:1!

Another dumb comment, what about sorting? Does <CC> and <CS> do this and we don't have to build it into the plugin (unless we're doing extraction into CSS files?)
See: https://github.com/atlassian-labs/compiled/blob/master/packages/css/src/plugins/sort-atomic-style-sheet.ts, but I don't recall where/how that's used in Babel.
