Start from the supplied overhead first frame. Locked camera over the same flat surface. Slide only the original top card to the right into the empty dashed destination outline. Keep that card approximately flat and retain its four corners and small plain marker. The other two original offset cards remain in place as a two-card stack. As the top card uncovers them, reveal only the existing blank card surfaces, with no artwork or extra layer invented. Do not bend the card around a spine, peel an adhesive corner, drag all three cards together or duplicate a new card. End with one separate original card at the destination and the same two-card remainder at the start position, then hold. No hand, cut or camera move.
