Duplex print — no taping or gluing needed. Fronts and backs are already paired and column-mirrored so they line up perfectly when flipped.

- Print pages 1–10 · Each front page is immediately followed by its matching back page
- Cut cards apart · Shuffle · Done — every card front aligns with its back
