/* Scoring64 help site — shared styles.
 *
 * The look is KKTeX's portfolio (kktexportfolio.klassikore.com) in another
 * colour: the same ivory ground, near-black ink, flat tinted panels with
 * generous radii and night panels, the same three type roles — a grotesque for
 * headings and UI, Noto Sans JP for Japanese, a mono for labels — and the
 * portfolio's clay swapped for Scoring64's teal as the one accent. */
