/*
 * The free-trial booking modal.
 *
 * Lifted out of style.css so the blog can use it. A reader who reaches the end
 * of "Is BJJ Good for Kids with ADHD?" and decides to come in should be able to
 * book from where they are, rather than being thrown back to the front page to
 * start again — which is what "Book a Free Trial →" used to do.
 *
 * Loaded by index.html and by every blog post, alongside booking.js.
