Create a 16-bit pixel art character izometric sprite sheet in PNG: perfect 3x3 grid (9 distinct frames) on solid pure white background, crisp edges, no shadows, no overlap. Same adult man design each cell: casual blue shirt, jeans, full body, feet touch bottom edge. Specify poses: Row1 (facing bottom-right): walking, standing, standing left-profile. Row2 (facing bottom-left): walking, standing bottom-left, walking away top-left (back). Row3: standing away (back), walking toward camera (front), standing front.
