Chibi Game Sprite Sheet Duo

Goal: Create a square pixel-art character sprite sheet for a cute anime game, featuring two chibi magical-idol girls: {argument name="white haired character" default="a petite girl with short white bob hair, bright blue eyes, a white-and-blue techwear jacket, cropped top, shorts, one black thigh-high stocking, belts, straps, and chunky blue sneakers"} and {argument name="pink haired character" default="a petite girl with long fluffy pink twin tails, pink-purple eyes, flower and bow hair accessories, a frilly pastel pink idol dress with ribbons, garters, and chunky pink sneakers"}. Canvas: Square 1:1 sprite-sheet canvas, dark navy background, no borders, no labels, no UI, no shadows except subtle pixel-art grounding. Arrange the characters in an evenly spaced grid with 4 rows and 8 columns, showing exactly 32 separate full-body chibi sprites. Layout and count: The sheet must contain exactly 32 discrete sprite poses. Row 1 has 8 sprites: white-haired front idle, pink-haired front idle, white-haired seated/knees-up pose, pink-haired seated/knees-up pose, white-haired three-quarter walking pose, pink-haired three-quarter walking pose, white-haired right-facing side walk, pink-haired right-facing side walk. Row 2 has 8 sprites: white-haired back-left view, pink-haired back-left view, white-haired full back view, pink-haired full back view, pink-haired full back view with slight shift, white-haired back-right walking view, white-haired left-facing side view, pink-haired left-facing side view. Row 3 has 8 sprites: white-haired front relaxed pose, pink-haired front relaxed pose, white-haired hand-to-mouth shy pose, pink-haired arms-open wink pose, white-haired jumping wink pose, pink-haired jumping arms-open wink pose, white-haired seated cute pose, pink-haired seated cute pose. Row 4 has 8 sprites: white-haired hand-on-hip pose, pink-haired neutral front pose, white-haired shy hand-near-face pose, pink-haired one-leg-up peace-sign wink pose, white-haired confident hand-on-hip pose, pink-haired peace-sign wink pose, white-haired front idle, pink-haired front idle. Visual style: High-quality 2D chibi pixel art with crisp outlines, soft anime shading, tiny game-sprite proportions, oversized heads, small bodies, expressive glossy eyes, clean cel-shaded highlights, pastel candy colors, and a polished gacha-game aesthetic. Keep the sprites consistent in scale, outfit design, face style, and line thickness across all poses. Character details: The white-haired girl uses a cool palette of white, black, and electric blue, with a short rounded bob, blue eyes, sporty futuristic jacket, asymmetrical black stocking, utility straps, and blue-accented sneakers. The pink-haired girl uses a warm pastel palette of pink, lavender, and white, with very long curly twin tails, bow and flower clips, frilly layered skirt, heart-like accessories, ribbons, lace accents, and pink platform sneakers. Constraints: Use {argument name="sprite style" default="cute chibi pixel-art game sprite sheet"}. Preserve the dark navy background and evenly spaced grid. Do not add text, logos, watermarks, weapons, props, scenery, or extra characters. The final image should look like an animation-ready character sheet for a small 2D game or GIF sprite set.
