  "walk": "Use case: identity-preserve. Use reference ONLY for approved character identity and pixel-art style. Production game sprite sheet: exactly EIGHT full-body frames in a FOUR column TWO row atlas, generous transparent gutters, no extra row. SAME homeless Johnny Silverhand-like rocker, dark shoulder-length hair, scruffy beard, sunglasses, chrome LEFT arm, worn black leather LONG COAT, dark jeans, brown boots. Camera sees him FROM THE BACK in EVERY frame. Large red Cyberpunk 2077 SAMURAI horned skull/flame emblem centered on coat back, small SAMURAI name above. Eight successive frames of WALK-IN-PLACE animation: hips, knees, arms and coat hem move gradually; heel lifts, passing legs, alternate foot contacts. He DOES NOT move away from camera and DOES NOT SHRINK. Exactly SAME camera distance and SAME body scale in all eight cells, full standing head-to-foot height constant, boots on common ground baseline, same lighting. All frames occupy about 85% slot height. Crisp gritty detailed pixel art identical to reference, not photo. No scenery, no labels, no borders, no shadows outside silhouette, true transparent background. Keep full boots visible."
