/*
 * yourbrainhealth.io: the site's stylesheet.
 *
 * Written for YBH in the contractor-free rewrite (slice 5, 2026-11-02) from the pages as they are
 * built, to draw them as the site has always looked. Vocabulary: config/theme-rename.json. The forms
 * (site/css/forms.css), the main menu (nav/css/nav.css) and what the behaviour modules draw
 * (site/css/behaviours.css) have their own sheets. Colours are Altior's brand palette.
 *
 * Contents
 *   1  tokens            6  bands: text, cards, split, pictures, media, clips, FAQ, form
 *   2  reset and base    7  posts and the post grid
 *   3  type and links    8  header and the menu drawer
 *   4  the frame         9  footer
 *   5  hero and banner  10  newsletter bar
 *
 * Breakpoints: 1599, 1399, 1239 (the arcs), 1019 (the drawer, smaller type), 767 (one column), 499.
