Help pick a syntax for CSS nesting survey results

Thank you to all of you that participated in helping CSS pick a nesting
syntax. The CSSWG has discussed the results and has
decided to move forwards with @nest. This unblocks the syntax issue, enabling
the @nest spec to move forward.

# Results

Out of 7,590 total votes, @nest was a clear winner:

87% of respondents voted for @nest, 5% for @nest always, and 7% for
brackets. Such a large split was not estimated but is relieving to the
discussions.

# What’s next?

The CSSWG will continue to discuss the feature and move on to other issues.
You’ve all helped us very much, we really appreciate the time you took to
evaluate the options and provide feedback.
