/* Markdown Prism — site styles
 *
 * The palette and the type pairing come from the app itself: the blue it draws
 * headings and links in, the orange its editor gives list markers, the grey its
 * code blocks sit on, and the two faces it shows side by side — monospace for
 * the source you type, the system face for what that source becomes. The page
 * is set in the same materials as the product, and loads no fonts to do it.
