*: clang-format all the things I've edited the formatting a bit. Now pointer asterisks (and reference ampersands) are on the variable instead of the type, as well as having newlines for function braces (but nothing else)

// Labels

.label-variant(@color) {
  background-color: @color;

  &[href] {
    &:hover,
    &:focus {
      background-color: darken(@color, 10%);
    }
  }
}
