/*
 * Certificate verification page.
 *
 * Plain CSS for the same reason as the chat widget and the nav drawer: the
 * theme ships without node_modules, so a rule that needs `npm run build:css`
 * before it renders is a rule that renders broken. The compiled main.css only
 * carries the utilities the templates already used, and this page needs status
 * banners, a spinner and a disabled button state that were never in it — so the
 * component lives here instead, keyed to the tia-cert__* classes in
 * student-certificate-page.php.
 *
 * Colours are the brief's palette, same values tailwind.config.js extends with.
