This copies what the other GaaP components will be doing for their
product pages.
The SASS and HTML is taken from here:
f05ca1fb71/source/stylesheets/modules/_breadcrumbs.scss
Only changes I’ve made are:
- making the file paths work with our build pipeline
Changes to our code to accomodate this are:
- putting the padding on the product page `<h1>` not its container
- moving the hero image accordingly so that it lines up
- making the `<main>` element on the product page into an anchor so that
the breadcrumb can link to it – screenreader will then announce the
link as “GOV.UK Notify, same page”
