Two changes:
1. why on earth is the `hover()` mixin used to apply the exact same styles than `:focus, :active, .active` stack above — which  doesn't use dedicated mixins… Removing mixin here seems a good thing since we can simplify selectors stack;
2. you're disabling a stylelint check for useless qualifying selector: `[type="radio"]` and `[type="checkbox"]` obviously applies to `input` elements, and removing this tag selector doesn't break specificity in that case.

Tried this locally without seeing any regression.
