      // we deliberately hardcode the number. This is to avoid unwittingly severely breaking the previous ESR in the event that:
      // (a) we happen to ship a new Bootstrap release soon after the release of a new ESR,
      //     such that folks haven't yet had a reasonable amount of time to upgrade; and
      // (b) the new ESR has unprefixed CSS properties/values whose absence would severely break webpages
      //     (e.g. `box-sizing`, as opposed to `background: linear-gradient(...)`).
      //     Since they've been unprefixed, Autoprefixer will stop prefixing them,
      //     thus causing them to not work in the previous ESR (where the prefixes were required).
