Art style: Children's Book.
A serene hilltop under a vast indigo sky filled with twinkling stars and a glowing crescent moon. A wide shot from a low angle looking up at the couple. Fireflies dance in the tall, dark grass, casting tiny yellow flickers. The atmosphere is quiet and magical, with deep navy and silver tones and a single soft spotlight effect from the moon hitting the center of the hill.

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.
