Blue Heart Wall Birthday Cake Number Candle Boy Portrait

[Purpose]
Convert the user's attached child photo into a minimal Korean birthday studio portrait, sitting on a small white chair beside a white cube pedestal holding a blueberry cream cake with an age-number candle, while blue paper hearts scatter diagonally up the white wall like they are floating out of the cake.

[Scene — image-to-image edit, preserve identity]
Use the user's attached child photo as the base. PRESERVE the child's identity: face proportions, eye shape, soft chubby cheeks, skin tone. The child remains recognizably the same. Realistic photographic tone (NOT illustration).

Korean Asian boy (around 1 to 3 years old), big delighted smile with eyes curving into happy crescents, one hand waving cheerfully near the cheek.

OUTFIT (FIXED, single default):
- TOP: a WHITE DRESS SHIRT with a NAVY BOW TIE at the collar.
- OVERALLS: NAVY SUSPENDER SHORTS (navy shorts with matching navy suspenders over the shoulders), neat and tidy.
- SHOES: small BROWN LOAFER SHOES with white ankle socks.

POSE + FURNITURE:
- The child sits on a SMALL WHITE WOODEN CHAIR at the right third of the frame, facing the camera, knees together, feet just touching the floor, one hand waving near the cheek in a joyful pose.
- At the left third: a WHITE CUBE PEDESTAL (about 45cm tall) holding the birthday cake.

CAKE + NUMBER CANDLE (HERO element):
- A round WHITE FRESH-CREAM CAKE (1 tier, about 18cm) on a white ceramic stand, decorated with soft cream swirls, a cluster of FRESH BLUEBERRIES around the top edge, and 2 small BLUE HEART PICKS.
- On top center: ONE NUMBER-SHAPED BIRTHDAY CANDLE displaying the digit "{age_number}", navy-and-gold striped candle with a tiny gold star, standing upright.

HEART BALLOON DECOR (HERO element):
- A clean WHITE STUDIO WALL fills the background.
- A cluster of 10 to 14 GLOSSY 3D HEART BALLOONS (puffy mylar and latex heart balloons in rich blue tones, sizes from 8cm to 22cm) rising DIAGONALLY UPWARD from just above the cake toward the upper-left corner, smaller balloons near the cake growing larger as they rise, with soft realistic highlights and gentle drop shadows on the wall for depth, like a stream of balloons lifting out of the cake.
- A delicate MINI HEART GARLAND (small blue felt hearts strung on thin twine) drapes softly across the upper-left wall above the balloon cluster.
- Balloons and garland stay on the LEFT and UPPER-LEFT region, leaving the area directly behind the child's face clean white.

FLOOR:
- Seamless white floor matching the wall, with a soft natural shadow under the chair and pedestal.

BABY PROMINENCE RULE (CRITICAL):
- Child is PRIMARY SUBJECT at the right third, full body visible from shoes to bow tie.
- Child's HEAD/FACE occupies about 18-22% of canvas height.
- The cake pedestal stays at the left, hearts on the wall, NOTHING covers the face.

[Text]
- The number candle displays EXACTLY "{age_number}" as the user typed it (1, 2, or 3 etc.), one clean digit shape.
- NO other text, NO logos, NO watermarks, NO studio names.

[Style]
Premium minimal Korean kids studio photography. Bright clean high-key lighting, crisp white tones with the blue accents popping, soft floor shadow, gentle film grain. Color palette: pure white + vivid blue + blueberry + navy-gold accent. Realistic photographic tone.

[Aspect]
3:4 vertical portrait, 1024 x 1366.

[IMPORTANT]
- Preserve the child's face, eye shape, skin tone, and natural proportions EXACTLY from the source photo.
- The number candle shows exactly "{age_number}" — a single clean digit, no extra characters.
- One hand waves near the cheek naturally, 5 fingers per hand.
- Heart balloons rise along the wall behind the child, not floating in front of the face; the area directly behind the face stays clean white.
- Baby is fully dressed in the shirt, bow tie, and suspender shorts.
- NO Instagram UI, NO captions, NO watermarks.
- Subject is a photographic, real child. Chair, pedestal, cake, and hearts are studio props.
