///
/// If enabled, the link styles will change. Underlines will:
///
/// - be consistently thinner and a bit further away from the link text
/// - have a clearer hover state, where the underline gets thicker to make the
///   link stand out to users
///
/// You should only enable the new link styles if both:
///
/// - you've made sure your whole service will use the new style consistently
/// - you do not have links in a multi-column CSS layout - there's [a Chromium
///   bug that affects links](https://github.com/alphagov/govuk-frontend/issues/2204)
