  "actor": "Use case: game-asset. Primary request: transparent 4 by 4 sprite animation atlas, exactly 16 equally spaced full-body poses of the SAME fictional homeless cyberpunk rocker, loosely reminiscent of Johnny Silverhand: long unwashed dark hair, scruffy beard, dark aviator sunglasses, weathered black leather vest under patched dark coat, faded grey shirt, worn jeans, battered boots, LEFT forearm a crude silver mechanical prosthesis. Friendly sardonic expression, no weapons. Consistent detailed hand-painted late-1990s Doom/Build-engine pixel art, not photographic, not smooth 3D render; muted cold skin and desaturated clothes with small warm highlights matching brick rainy night alley. Clean transparent gutters, no background or ground shadows. All poses face the viewer or turn slightly left with consistent proportions, camera and illumination, full boots visible. Exactly four columns and four rows read left to right. Frames 1-4 crouching on bent knees, leaning toward someone seated on the ground, raising RIGHT natural hand to wake them; frames 5-8 still crouched, subtle mouth speaking and beckoning hand gesture; frames 9-12 smoothly standing from crouch; frames 13-16 turning to his left and walking past the seated viewer. Shared cell coordinates, identical SCALE between poses: crouched poses must be shorter than standing, do NOT enlarge crouched bodies to fill the cell. All feet on the same cell baseline, maximum standing figure occupies 84 percent of cell height, crouched 55 percent, enough headroom. No text, no labels, no logo, no duplicates, no cropped limbs. True transparent background.",
  "lighter": "Use case: game-asset. Primary request: first-person LEFT HAND opening and igniting a battered silver flip-top lighter, transparent 4 by 4 sprite animation sheet with exactly 16 equally spaced frames. Crisp late-1990s Doom/Build-engine shaded PIXEL ART, not photographic, not flat cartoon. Adult light skin left hand, black worn leather jacket sleeve entering from lower LEFT of every cell. Natural anatomically correct fingers and LEFT thumb on spark wheel. NO RIGHT HAND, NO CIGARETTE. The ignition flame is meant to light a separate cigarette supplied by the game. Camera looking down at the lighter. Same hand identity, scale, position anchors and warm/cool lighting across all cells, clean transparent margins. Sequence read left to right: frames 1-3 closed lighter raised, frames 4-6 lid opens and thumb rolls spark wheel with tiny sparks, frames 7-12 bright small warm yellow flame fluttering ABOVE nozzle near the upper centre of the cell, frames 13-14 thumb stops flame and lid closes, frames 15-16 closed lighter lowers a little. Lighter nozzle always near x=50 percent, y=20 percent of cell, fingers and wrist below it; no flipping hand orientation. Solid opaque skin/metal/leather, transparency ONLY outside silhouettes and tiny flame wisps. No text, lettering, border, shadow matte or background. One square sprite sheet, exactly 4 rows by 4 columns.",
  "knees": "Use case: game-asset. Asset: transparent first-person foreground sprite, wide landscape composition. View of one's OWN bent knees and shins in faded charcoal-blue jeans while seated on the ground of a rainy alley, knees occupying bottom left and bottom right edges, a clear transparent wide gap through the centre and entire upper half, trouser legs descend out of the bottom edge naturally. NO HANDS, NO arms, NO other person, NO background, NO shoes in top area, NO cigarette, NO text. Detailed hand-painted late-1990s Doom / Build engine pixel art with crisp pixels, muted cool denim and subtle warm edge highlights; not photoreal or smooth render. Large creased bent kneecaps at left and right lower corners, believable seated first-person perspective, consistent player black jacket/jeans character. True transparent background outside legs.",
