/**
 * Frequently Bought Together: the block on a product page. Free.
 *
 * A quiet card inside the product form: a strip of pictures (what is not
 * ticked is faded), then stacked rows, one per product, each a tick, a name,
 * and a price on the right. Never a carousel. It borrows the theme's font and
 * text colour, so it sits in any shop; the only fixed colours are greys and
 * the green tick for what is already in the basket.
