/*
 * Netresearch brand styling for the nr_browser_ai demo page.
 *
 * Fonts are self-hosted: the page must issue no third-party request, both
 * because it argues for on-device processing and because hotlinking a font CDN
 * is not an option for a German company.
 *
 * Teal #2F99A4 reaches only 3.38:1 on white, so it is used for large text, fills
 * and borders only. Body-size teal text uses #15585E (8.1:1) and teal fills
 * carrying normal-size white text use #257880 (5.2:1).
