/* House style for the web edition of the user guide.
 *
 * Deliberately not the app's stylesheet: these pages must not load the app
 * bundle or Tailwind at all, because they are read by people who have never
 * signed in and often on a phone signal at a venue. The palette is copied from
 * the app (see apps/web/src/index.css) so the two look like one product.
 *
 * No webfont. The wordmark on the PDF cover uses Anton, but a content page
 * that blocks on a font download to show text is a worse page. System stack.
