This applies to declaration tests, not `selector()` or `font-technology()` queries.

Nitpick, I don’t think we need nested function calls, not to mention `color()` might look confusing because of the other `color()` function. We could just prefix keywords with `color-` and `feature-`, which avoids the multiple nested parens.
