Doodle Birthday Card

[Purpose]
Convert the user's attached child photo into a doodle-style Korean kids birthday card with hand-drawn stickers, speech bubbles, and a crown. Cute scrapbook/stationery (다꾸) aesthetic for SNS sharing and birthday party use.

[Scene]
The child's face from the attached photo is the photographic centerpiece. Everything else around it is hand-drawn illustration in the same marker-pen style.

Cutout placement:
- The face/head cutout occupies about 28-32% of the canvas height, positioned in the upper-center (top of head around 18% from canvas top, chin around 50% from canvas top).
- If the source photo shows natural shoulders, preserve them photographically as part of the cutout.
- If the source shows only the face (close-up), draw a small handdrawn rounded shirt collar (clean white #ffffff, thick black marker outline, gender-neutral round-neck) directly below the chin to suggest a body.
- The cartoon hands holding the heart appear directly below, connecting naturally.

Composition (square 1:1):
- Outer frame: solid {bg_outer_color} background with a {bg_inner_color} rounded scalloped inner frame filling ~92% of the canvas.
- Top headline (above the head): white rounded sticker patches stacked, containing "HAPPY" in {headline_color_1} bubble-letter handdrawn font and "BIRTHDAY" in {headline_color_2} bubble-letter handdrawn font. A small handdrawn number sticker "{birthday_age}" sits next to the headline.
- Crown: a small handdrawn crown/headpiece sitting on top of the head. {crown_style_detail}.
- Left and right of the head: two small handdrawn speech-bubble stickers with vertical Korean text "모두 축하해줘" inside.
- Top corners: small handdrawn speech bubbles with "축하해".
- Bottom centerpiece: a large handdrawn pink heart held by two tiny handdrawn cartoon hands (visible at the bottom edge). Inside the heart: the text "{child_name}" in white handdrawn font.
- Scattered stickers across the canvas: small handdrawn cartoon bees (yellow+black, smiling), daisies (white petals with yellow centers, smiley faces), small flowers, stars, sparkles, small confetti dots, small numbers ("{birthday_age}", "6", "9"), tiny hearts — all in the same handdrawn marker-pen style.

[Style]
Korean kids' doodle/sticker-book (다꾸) aesthetic. Hand-drawn cartoon outlines with thick black marker pen contours (about 3-4px), filled with bright flat colors. Slightly imperfect handdrawn lines for charm.
Palette: {palette_description}.
Fills: flat bright colors, no gradients, no shadows, no 3D effects.
The face cutout is the only photographic element; everything else is illustrated.

[Text]
All Korean and English text in handdrawn bubble/marker font (cartoon hand-lettering, not standard sans-serif).
- "HAPPY" in {headline_color_1}, "BIRTHDAY" in {headline_color_2}.
- "{child_name}" inside the heart in white handdrawn.
- "{birthday_age}" as small number sticker near the headline.
- "모두 축하해줘" vertically in two speech bubbles (left and right of the head).
- "축하해" in small bubbles at the top corners.

[Aspect]
1:1 square (1024x1024), full bleed.

[🚫 IMPORTANT]
- Preserve the child's face from the original photo EXACTLY — facial features must remain identical
- Korean text must be precise: "모두 축하해줘", "축하해", "{child_name}"
- Cutout sizing follows the 28-32% canvas height rule
- Only the face cutout is photographic — every other element is handdrawn cartoon style
