At the time of publishing there were several bugs in postcss-calc affecting how
css-custom-properties are handled in calcs.
https://github.com/postcss/postcss-calc/issues/77
https://github.com/postcss/postcss-calc/issues/107
https://github.com/postcss/postcss-calc/issues/103
https://github.com/postcss/postcss-calc/issues/91

This was breaking the Utopia type-scale calculations at the heart of the frontend.
So we disable CSSNano doing anything with calcs.
