Animate the pointing hand and sleeve as one rigid piece pivoting from offscreen at the lower right. It starts resting low at the bottom, then swings upward in a smooth arc until the index finger points vertically and touches the third thumbnail from the left in the upper row. At contact, make a small wrist rotation: keep the fingertip fixed on the card, rotate the hand slightly counterclockwise, then rotate it back. Immediately after this touch, move the entire upper row of video thumbnails left by about two thumbnail widths as one continuous carousel strip, with outgoing cards clipped at the left edge and identical incoming cards entering from the right; keep the individual play buttons locked inside their cards. The hand then translates downward and slightly left while rotating the forearm counterclockwise, reorients so the index finger points toward the lower row, and performs a second tap near the upper edge of the second thumbnail from the left in the lower row by repeating the same small fingertip-fixed wrist rotation. After the second touch, slide the lower row left by the same distance in the same carousel manner while the upper row holds still. Finally, rotate and translate the arm back down so it returns to where it sits at the bottom in the provided SVG, with the grid settled into the arrangement shown in the provided SVG.
