[Core Structure — 3-band layout, all elements rendered as line art]
- Header (top 22%): a cute outlined ribbon banner at the top with the Korean title "{title}", a small class label "우리 반 미술놀이" centered above the banner, and a tiny pencil icon near the banner.
- Instruction strip (just below header, full width): "✏️ 좋아하는 색으로 예쁘게 칠해 보세요" in friendly Korean handwriting.
- Practice box (upper-right corner): a small rounded rectangle box containing "따라 써요:" label at top-left, and the word "{practice_word}" rendered LARGE in dotted-line Korean tracing font (점선체) below the label.
- Age badge (just below the practice box): a small text label "{difficulty_age_label}" — simple Korean text only, NO star icons or symbols.
- Central hero area (middle 58%): the main illustration {scene} as the biggest silhouette in the center, simplified into rounded child-friendly shapes with thick outer contour lines and large color-in regions.
- Footer (bottom 20%): two input lines "이름: ___________" and "날짜: ___________" side by side, plus a small circular badge stamp at the bottom-right corner with the text "참 잘했어요" in two lines.
- Corner accents: small flower, heart, leaf, and sparkle doodles at the top-left, top-right, bottom-left, and bottom-right corners — outline-only.

[Style Rules]
- Typography: Any visible typography must be simple Korean worksheet text, accurately rendered and placed as part of the printable activity page. Korean texts to render: "{title}", "우리 반 미술놀이", "✏️ 좋아하는 색으로 예쁘게 칠해 보세요", "따라 써요:", "{practice_word}", "{difficulty_age_label}", "이름:", "날짜:", "참 잘했어요".
- Color palette: Black line art on pure white paper. NO colored fills in the final output, only empty white regions intended for coloring.
- Ink style: Polished coloring-book illustration style with thick outer contours, slightly thinner internal lines, smooth curves, and friendly hand-drawn charm.
- Page decoration: Outlined decorative frame, corner doodles, small badge shapes, tracing box, reward sticker circle — all colorable and print-friendly.
- Workbook realism: The sheet should feel like a real Korean children's activity page, with clear section dividers, cheerful labels, and balanced educational worksheet elements.

[Visual Style]
- Camera / lens: Flat scanned worksheet look, top-down orthographic layout, print-ready illustration sheet.
- Lighting: Even neutral studio scan lighting with zero directional shadow, no highlights, no reflections.
- Color grade: Pure monochrome line art on white paper, high-contrast black ink look.

[Mood]
Korean preschool worksheet illustration — cheerful printable coloring-book page feel, like a polished activity sheet from a kindergarten workbook with playful story details, cute learning labels, and inviting areas to color.

[CRITICAL — Korean text accuracy]
Render ALL visible Korean text correctly and clearly, character by character, with NO broken or misrendered Hangul. The exact Korean strings to appear on the page are:
  1. Title (in the ribbon banner): "{title}"
  2. Class label (above banner): "우리 반 미술놀이"
  3. Instruction strip: "✏️ 좋아하는 색으로 예쁘게 칠해 보세요"
  4. Practice box label: "따라 써요:"
  5. Practice word (large dotted tracing font): "{practice_word}"
  6. Age badge: "{difficulty_age_label}"
  7. Name input label: "이름:"
  8. Date input label: "날짜:"
  9. Reward stamp (in circular badge): "참 잘했어요"
Double-check each Hangul character. Do not abbreviate, transliterate, or substitute.

[CRITICAL — Composition & coloring usability]
- The main subject must remain centered with the largest size.
- All outlines must be smooth, closed, and thick enough for printing (검정 굵은 외곽선 3~5px).
- Keep most interior spaces large and easy to fill with crayons or markers.
- If any characters or animals appear, give them cute, child-friendly proportions with clear facial features and friendly expressions.

[🚫 PROHIBITED]
- Broken or misrendered Korean characters
- Any colored fills, gradients, shading, halftone, crosshatching, or sketchy double-lines
- Tiny fussy details that are hard for children to color
- Star icons or symbols in the age badge area — text label only
- Realistic, 3D, photographic, anime, or manga style
- Fake official seals, certifications, or celebrity likenesses
- Real brand logos — original cute characters only
