/* Sayful Pro checkout hand-off.
 *
 * This page exists for about two seconds: the buyer arrives from the native app
 * having already decided, and the Paddle overlay opens on top of it. So it is
 * built as a confident receipt, not a billboard — quiet, atmospheric, and out of
 * the way.
 *
 * The serif display face is deliberate: the app's own `DisplayText` renders with
 * `design: .serif`, so a sans-only page reads as a different product at exactly
 * the moment trust matters most.
