 * KubeCrow shared styles: fonts, colours, header, footer, buttons, cards, copy boxes and install steps.
 * The same file is served by kubecrow.com and app.kubecrow.com so the two look like one site. Edit it here
 * (kubecrow-website/public/shared.css), then copy it into kubecrow-app with `node scripts/sync-shared.mjs` there;
 * scripts/check-site.mjs fails while the two copies differ. Each site's styles.css loads after it and holds only
 * that site's own pages. The Ocean palette: dark first, light via media query.
