  "initial": "Use case: stylized-concept. Asset type: transparent character atlas for ThetaHerd website day/night theme. Input image 1 is character style reference only (original friendly Cattle ghost cow). Input image 2 is the approved visual direction, reference only, especially the solid warm brown bull. Generate exactly ONE transparent 1536x1024 image, divided invisibly into FOUR equal columns and TWO equal rows, each cell 384x512. Exactly eight separate full-body clay-toy characters, each centered in its own cell with generous empty transparent margin and completely contained; no character crosses a cell boundary. No grid lines, no captions, no scenery, no floor, no drop shadow, no text, no UI. Columns are identities: column 1 solid white COW with lavender spots, small lilac horns, pink muzzle, four little legs; column 2 solid warm caramel BULL, broader curved cream horns, four legs and tail; column 3 GHOST COW, same white/lavender/pink identity, legless floating tapered scalloped ghost tail; column 4 GHOST BULL, warm ivory/lilac glow with broad bull horns, pink-brown muzzle, legless floating tapered ghost tail. TOP ROW DAY: solid cow and solid bull awake and friendly; ghost cow and ghost bull peacefully asleep, closed eyes and tucked little arms, floating bodies still visible. BOTTOM ROW NIGHT: solid cow and solid bull lying asleep with folded legs and closed eyes; ghost cow and ghost bull awake, friendly dark oval eyes, with subtle lavender moonlight rim lighting. The day and night identities must match precisely. Soft matte clay surface, rounded anatomy, charming high quality game-companion art, consistent sizes, three-quarter front view. Real transparent alpha everywhere outside each figure. No money, shields, arrows, symbolic writing, sparkles, words or checkerboard.",
  "repair": "Edit the supplied character atlas. Preserve all eight identities, clay style, facial expressions and the exact four-column two-row ordering. Fix only extraction and spacing: remove ALL gray/brown/lilac backdrop haze, colored glow and ambient background pixels so the entire space outside the actual animal silhouettes is fully transparent alpha 0, NOT translucent or painted checkerboard. Keep each animal itself opaque except a subtle edge on the ghost bodies. Fit each animal at 80% of its current width and height, centered within its existing equal 384x512 cell on the same 1536x1024 canvas. Make the whole cow tail fit INSIDE column 1; nothing from any figure may cross a cell edge. No floor shadow, no ground, no stars, no text. The result is eight clean independently usable website cutouts on one genuinely empty transparent atlas.",
