Use case: illustration-story
Asset type: one vertical production master (1024x1536) for a hand-drawn Chinese diary-comic video. This single output will be locally split into a handwritten caption plate and a color illustration plate.
Input images: the supplied original-video frames are style references; the fixed protagonist character sheet is the identity reference. Ignore all text in references.
Narrative sentence to illustrate: "画里的风筝，比窗外飞得更高。"
Scene direction: Stage one simple visual beat that expresses only the current sentence.
Create one concrete, immediately readable tableau for that sentence. Use the locked recurring protagonists whenever the current sentence requires them.
Character lock: 重复出现的主角须保持同一张脸、发型、年龄、服装配色和身体比例；具体人物身份以故事原文为准；不得添加原文未提及的配角、道具或文字
Style: minimalist Chinese diary comic reconstructed from the supplied reference video, pure white background, uneven black felt-tip pen outlines, naive wobbly proportions, rough dense black crayon scribbles for dark areas, sparse props, abundant negative space, selective muted wax-crayon color only, no realistic shading, no paper texture, no watermark
Top copy panel (pixels y=0–342): pure white background. Write ONLY this Simplified Chinese caption verbatim, preserving the explicit line breaks:
"画里的风筝，比窗外飞得更高。"
Use thick casual black felt-tip handwriting, 1–3 lines only, generous 48-pixel left/right margins, and a large readable letter size. Do not put any illustration or decorative mark in this panel. Do not place text below y=342.
Illustration panel (pixels y=512–1536): use this exact lower 1024×1024 square for the scene. Leave the 342–512 transition band completely white.
Composition: use a comfortably wide camera view. Keep the entire sparse scene in the lower-middle of its illustration square with generous white negative space. Reserve a clean white safe border of at least 10% on the left and right and 8% on the top and bottom. Every figure, limb, prop, building edge, roof, tree branch, rain stroke and motion mark must stay completely inside that safe border. Scale the scene down when necessary; never let any visible mark touch or cross a canvas edge.
Color: selective muted wax-crayon color only: sage green, dusty blue, warm tan, brick red and warm yellow. Keep hair, trousers and other dark areas as black scribbles. Leave skin and most of the canvas pure white.
Continuity: preserve the locked character design. Use the fixed character sheet only for the protagonist's identity, never copy its pose or composition. Include only people required by the current narrative sentence.
Narrative isolation: the character lock defines identities, not an automatic cast list. Show only characters explicitly named in the current sentence or strictly required for its immediate action. Never add family bystanders. Never show a future daughter, rescued child, grandmother, father or any other supporting character before that person is introduced by the narration. Do not carry any person, prop or setting forward merely because it appeared in another scene.
Constraints: non-graphic, emotionally restrained family storytelling; no visible impact, blood, wounds, bruises or injury; no cropped or partially visible subject, prop or background structure; no close-up framing; no extra text outside the exact top caption, no letters or numbers in the illustration, no labels, captions, speech bubbles, logo, signature or watermark; no graphite realism, gradients, detailed scenery or vector cleanliness.
