Begin with the shield hidden and the person reset to an upright pose on the upper-left/top step while the staircase stays fixed. Animate the person as one rigid icon translating diagonally down and to the right along the stairs, easing between positions as if losing balance and sliding feet-first; rotate the figure from a more upright/forward-leaning angle into a reclined angle with the head trailing left and the legs reaching down-right. After the slide settles near the lower-right steps, pop the shield into the foreground over the person: scale it up quickly from nothing at its final center, overshoot slightly, then settle back to its size in the provided SVG, covering the overlapping parts of the person. After the first shield pop settles, cut back to the initial no-shield pose and repeat the same falling motion once more, ending with the shield visible in front.
