/*
 * The page builder's reference bands.
 *
 * Loaded on every page, after apiit.css and mediaquery.css, so it builds on
 * the site rather than fighting it. Everything here is a band the builder
 * can place that the site had no shared stylesheet for: the event intro,
 * the picture tiles, the info cards, the offer band, the link cards, the
 * save-the-date card, the quote cards, the pathway steps and the two-colour
 * band. The rules are lifted from public/assets/css/open-day.css and
 * public/assets/css/alsinc.css - the pages those bands were first built on -
 * and renamed with a blk_ prefix so a band placed anywhere matches the one
 * on the page it came from.
 *
 * Anything the site already has (buttons, headings, the four red squares,
 * the form controls) is used as it is and is NOT restyled here.
 *
 * apiit.css sets p { font-size: 14px !important } for the whole site, so no
 * copy wrapper here sets a size: an editor's paragraphs read at 14px in these
 * bands exactly as they do on every other page.
 *
 * Lists are always two class names deep (.blk_chips li.blk_chip): apiit.css
 * has `.container ul li { display: list-item; list-style-type: disc;
 * margin-bottom: 20px }` for editor-written prose, which beats one class.
