Fix SASS Deprecation Warning

[indus]

Sass's behavior for declarations that appear after nested
rules will be changing to match the behavior specified by CSS in an upcoming version. To keep the existing behavior, move the declaration above the nested rule. To opt into the new behavior, wrap the declaration in & {}.

More info: https://sass-lang.com/d/mixed-decls

There may be more locations where these changes should be made - but this one is the only one that gives an error in my codebase

I came here to propose the same fix. Thanks for doing this already.

@indus, I'm conflicted on this — while we do need to address this future breaking change, simply adding & {} everywhere results in multiple :root {} blocks in the final CSS. That makes the files harder to read, heavier, and could also lead to longer browser render times.

For now, I’ll silence the warning when compiling Sass. Open to revisiting if we find a cleaner way to handle it.

Hey @indus, after looking into this further, I found that @nstringham’s approach in PR #596 provides a clean solution by reordering declarations instead of adding extra & {} wrappers. This keeps the final CSS lighter and more readable.

I’ll likely move forward with that fix, but I appreciate your contribution and the discussion around this!
