/* QUADRAQ site 1.5.0 — application chrome.
 *
 * Board and Line load this file and get the site's header, buttons and typography without
 * rebuilding them. Everything below the header belongs to the app: this stylesheet only
 * covers what has to look the same in both.
 *
 *   <link rel="stylesheet" href="/shared/quadraq-ui.css">
 *
 * The tokens are the brand ones. Use them instead of writing colours by hand, so a change
 * to the palette reaches both apps at once.
