Chibi Nezuko 4x4 Sprite Sheet

Goal: Create a 4×4 pixel-art sprite sheet of Nezuko Kamado as a cute chibi action-game character, suitable for turning into an animated GIF or game attack sequence.
Canvas: Wide white canvas, clean empty background, arranged as an evenly spaced 4 columns by 4 rows grid. Each cell contains one full-body sprite with a soft gray contact shadow. Add a small hot-pink rounded number badge in the upper-left of each cell, labeled exactly 1 through 16 in white.
Character design: Chibi anime girl with a large head, small body, pale skin, bright pink eyes, long dark brown wavy hair with orange-tinted tips, a small pink bow on one side of the hair, and a green bamboo gag across her mouth. Outfit is a pink patterned kimono under a dark brown haori cloak, pale pink obi, white leg wraps, and pink sandals. Use saturated colors, crisp pixel-art edges, soft anti-aliased highlights, expressive action poses, and a cute but fierce demon-slayer-game feel.
Layout and 16 required frames: Include exactly 16 discrete sprites, numbered and posed as follows: 1 standing idle facing forward, hands near chest, calm expression; 2 running or dashing to the right with hair streaming left; 3 crouched combat stance facing right, angry eyes, cloak flaring; 4 spinning slash attack with a bright pink circular energy arc around the character; 5 continuation of spinning attack, body turned left, large pink crescent trail sweeping around; 6 mid-run leap with flower petals, one arm forward; 7 rear-facing spinning motion, hair and cloak spiraling with a pink circular trail; 8 frontal power-up or slash impact pose with tall pink energy spikes rising on both sides; 9 low high-speed dash to the left with horizontal pink speed streaks behind; 10 airborne running jump, knees tucked slightly, petals floating; 11 side slash pose facing right, one arm extended, pink crescent energy arc to the right; 12 relaxed standing pose angled slightly right, petals around, hair flowing; 13 low crouch on hands and knees, fierce eyes, ready to pounce; 14 low sweeping spin attack, body close to ground, large pink crescent trail wrapping around; 15 back view standing/walking away, cloak and hair covering most of the body, orange hair tips visible; 16 front-facing shy idle pose, feet together, hands close, wide pink eyes.
Effects: Use cherry blossom petals and pink motion trails in many frames, especially frames 4, 5, 7, 8, 9, 11, and 14. Keep effects contained inside each grid cell and do not overlap between cells.
Style constraints: Pixel-art sprite sheet, chibi proportions, consistent scale across all frames, no scenery, no UI besides the 16 number badges, white background, high clarity, animation-ready poses, cohesive lighting and colors.
