   The preview is the soul of the hero. On load it unfolds like a fresh
   ledger page being opened from a book, then each row hand-writes onto
   the page left-to-right (a clip-path inset wipe stands in for ink).

   - Outer card: rotateX(-72deg) + scaleY(.5) + blur, settles at 0/1.
   - Children: 7 rows stagger via :nth-child, each ~520ms wipe.
   - Total runtime ~2.0s, lands flat and readable.
   - prefers-reduced-motion: instant, no animation.

   The inline-style block kept the original visuals when the preview
   was static. The styles now live here so the @keyframes can hook in.
