Pastel Cat-Eared Anime Girl

Create a full-body kawaii anime VTuber-style illustration of a cheerful cat-eared girl mascot, centered on a clean white background with pastel magical effects. The character is a petite teenage-looking anime girl with {argument name="hair color" default="silvery lavender-blue"} wavy shoulder-length hair, soft bangs, bright cyan-blue eyes, rosy cheeks, and an open happy smile. She has large cat ears with pink inner ears and dark outer tips, decorated with ornate gold-and-white floral hair accessories, small chains, beads, and a pink ribbon bow. Pose her dynamically as if floating or skipping forward: one hand raised close to the viewer in a friendly wave with five fingers visible, the other arm extended outward, one leg straight down and the other bent back playfully. Outfit: pastel blue oversized cropped jacket with puffy sleeves and white drawstring bows, pale blue shirt, white asymmetrical overall-style skirt/shorts dress with visible straps, buttons, seams, a white belt with crossing straps and small gold bow charm, layered light-blue ruffled shorts underneath, one white knee sock, one oversized blue leg warmer with bow details, and light blue-and-white sneakers. Add a tied ribbon accessory and small dangling charm at the hip. The color palette should be soft baby blue, white, pale pink, and gold accents, with delicate cel-shaded anime rendering, clean line art, glossy eyes, soft gradients, and high-detail clothing folds. Surround her with a circular aura of pastel pink and blue sparkles, glowing starbursts, bokeh dots, and floating heart-shaped petals; include exactly 3 large pink heart petals, 5 medium blue heart petals, and many tiny pink petals and miniature flower shapes scattered around the frame. Make the composition vertical, full body visible from head to shoes, airy and bright, with no text, no watermark, no extra characters, and a polished Japanese mobile-game character key visual look.
