/* XAICG website.
 *
 * The page follows the product's design system: a deep near-black canvas
 * holding white type and one accent, yellow (#FCD535), which carries every
 * primary action, the wordmark and the claims worth shouting. Cards are flat
 * blocks a step lighter than the canvas; depth comes from that contrast,
 * not from shadows or gradients. Corners are tight (6 to 12px), headings
 * are bold, every number is set in its own typeface, and the page closes on
 * a light footer. Sections that are about doing something (the steps, the
 * prices) flip to a light surface with the same yellow buttons.
