Use case: precise-object-edit. Asset type: transparent sprite atlas for a realistic 2D website animation. Reference image: original white stork standing in profile, preserve feather texture, colors, proportions and soft daylight. Create ONE landscape atlas in a clean 3-column by 2-row grid, six isolated poses of this exact same stork, equal-size cells with ample transparent margins. No grid lines, no text, no nest, no ground shadow. Actual transparent background. Fixed camera and identical body scale in all cells, not cartoon. Row1 col1: original standing stance facing left, both feet planted. Row1 col2: same body and feet exactly, only head looks toward camera in a three-quarter view (beak foreshortened, visibly changing direction). Row1 col3: same body and feet exactly, head turned farther toward camera and slightly right (neck anatomically natural, body stays in profile). Row2 col1: weight shifted onto right leg, other leg visibly relaxed and bent, body only slightly lower. Row2 col2: intermediate crouch, legs folded at joints, body halfway down toward resting on nest, beak normal left-facing. Row2 col3: fully sitting resting white stork, legs folded beneath body, compact natural seated body, head upright looking left. Match the feather and beak appearance across all six poses. Separate poses completely, keep every beak and toe inside its cell.
