      "prompt": "Use case: stylized-concept. Production game character expression atlas for a Korean Hwatu game, art direction 'Hwawol Hall': sophisticated friendly modern Korean minhwa folk painting, ink contours, softly textured opaque gouache, warm ivory, cinnabar, pine green, muted gold. Create ONE exact rectangular sprite atlas, 4 columns by 3 rows, equal square cells, ideally 2048x1536. Every cell contains one centered waist-up portrait entirely within the central 80% of its cell, with equal size and baseline; no labels, no frame, no text, no cards. Actual transparent alpha background across all empty space; no checkerboard drawing. ROW 1: same friendly stocky traditional Korean minhwa tiger, orange coat with expressive dark stripes, cream muzzle and teal hanbok vest. ROW 2: same clever Korean magpie, blue-black and ivory feathers, warm red small hanbok collar. ROW 3: same endearing Korean dokkaebi, warm coral skin, one small horn, dark short curls, mustard hanbok jacket, no weapons. For EACH row, columns left to right are neutral warm welcome; concentrated focused eyes; delighted broad joy; disappointed gentle sad expression. Consistent identity and clothing across four expressions, clear emotionally different faces readable at 48px. Culturally Korean folk painting influence rather than anime, Japanese oni or western cartoon. Playful but for adults, elegant hand-painted rhythm and lovely individual facial details. High production quality, restrained natural brush texture, clean legible silhouettes. Flat front-facing or slight three-quarter portraits with no perspective grid and no scene background. Keep all twelve separate with generous gutters.",

      "role": "Lobby Korean hall environment",
      "prompt": "Use case: stylized-concept. Asset type: wide background illustration for a Korean traditional Hwatu browser game lobby named Hwawol Hall. A welcoming empty Korean hanok club room at late afternoon, viewed from just above a low wooden table covered in deep pine green felt, table near center-bottom. Warm cream paper sliding doors, old ochre wood columns and beams, a restrained Korean minhwa pine tree painting on right wall, open wooden veranda on left with garden stone and red autumn maple glimpse. Natural amber sunlight across the wooden floor, quiet and refined rather than fantasy or lavish casino. Hand-painted contemporary Korean folk-art illustration, delicately irregular ink contours, matte gouache texture, cel-like shading with believable shallow depth, cinnabar accents and jade-green textiles. Wide landscape composition 3:2; large calm uncluttered dark green table surface for future game interaction; a gentle room vignette and genuine layered space. No characters, no people, no visible playing cards, no interface, no text or labels, no numbers, no logos. Do not render a website mockup. High quality original game environment painting, crisp enough for a large desktop display, not photorealistic and not Japanese tatami.",
