Art style: Children's Book.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Leona, a cheerful five-year-old birthday girl. She has soft rounded cheeks, warm fair skin, big bright brown eyes, a wide happy grin showing little teeth, and shoulder-length wavy chestnut-brown hair pulled into two loose pigtails tied with pink ribbons, a small glittery party crown perched on top. Slim little-kid build, short arms and legs. She wears a puffy pastel-pink party dress with a tulle skirt, a sparkly silver waist sash, white ruffled ankle socks, and shiny mary-jane shoes. She holds a small colorful balloon, beaming with excitement. Setting: a festive living room decorated with paw-print birthday banners, streamers, and a big cake on a table behind her.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Children's Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Children's Book". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Children's Book" idiom, not in any other medium.
