/* Haiyo — landing page.
   Two layers of styling:
   1. The site itself: an editorial, typographic frame (serif display, mono labels, hairlines).
   2. Product replicas: rendered with the app's own tokens and font stack so they read as the
      real app (values mirror src/styles.css). Replicas respond to their container, not the
      viewport, so the same markup works pinned full-width or squeezed onto a phone. */
