Art style: Children's Book.
A sun-drenched, vibrant playground with a tall wooden slide and swings. The ground is covered in soft golden sand and patches of green clover. A wide-angle shot from a low perspective looking up at a red balloon floating away. The atmosphere is bright and energetic, with a palette of sky blue and grassy green. A boy reaches upward with an expression of worry while a girl nearby stands ready to jump.

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.
