/* Poof! manual: "Paper & ink", the look of the Poof! website.
 *
 * Loaded after extra.css and overriding it. Warm paper with a faint grain and near-black ink
 * (light), warm charcoal with cream type (dark); a serif display face for the page title and
 * headings, a sans for text, and vermilion as the one accent (links, the page you are on, the
 * primary button). The tokens are the website's own (its poof.scss, Paper & ink).
 *
 * Fonts: nothing here loads a font. The in-app manual uses the system stacks below (Georgia
 * for display, the system sans for text). The website build (scripts/build_manual_site.sh
 * --web-fonts) adds Fraunces and Instrument Sans from Google Fonts and a small stylesheet that
 * sets --paper-display and --paper-sans to them.
