Using an uploaded photo or a synthetic reference photo, create a vertical 3:4 before-and-after comparison poster. If multiple photos are uploaded, create one separate poster for each photo; do not mix different photos on the same page.

IMPORTANT PERSON SAFETY
If the reference contains a real person, do not preserve or recreate the exact identity, exact face, or biometric likeness. Replace adults with a non-specific refined East Asian / Eastern person, beauty, model, or editorial figure, and replace children with a cute, healthy, natural East Asian / Eastern child when relevant. Preserve only the broad pose, action, composition, clothing color family, lighting mood, and scene structure.

LAYOUT
The upper and lower sections should each occupy exactly half of the total height, with a seamless transition between them. Do not add borders, arrows, or Before / After labels.

TOP SECTION: ORIGINAL PHOTO
The top section should use the uploaded or generated reference photo, filling the full width of the canvas. Preserve the subject type, pose/action, scene, natural lighting, and dominant color palette. Only allow subtle overall color adjustments; do not change the atmosphere or add any filter effects. Maintain the photo's original aspect ratio and do not stretch the subject. To fit the top section, crop only unimportant edges; if cropping would remove the main subject, add a small amount of plausible background instead.

BOTTOM SECTION: GEOMETRIC ABSTRACT
Using the same photo from the top section as the only reference, recreate the core subject and a few key environmental elements as a hard-edged, geometric, flat-style illustration. Do not add people, animals, objects, or actions that were not present in the top photo. Preserve the core subject's left/right position, pose, direction, interactions, and major occlusion relationships so the two sections appear visually aligned at first glance.

Remove secondary background elements and insignificant details. The subject may be scaled down slightly to create generous negative space around it. Construct objects using a limited number of polygons of varying sizes, simplified curves, and solid color blocks. Preserve enough of the subject's silhouette, movement, and defining characteristics so it remains recognizable as the same kind of subject, not a generic icon.

Use adjacent color blocks of different shapes and brightness levels to define structure. Do not use gradients, outlines, 3D shadows, or realistic textures. Extract approximately 5-6 representative colors from the upper photo and organize them into a cohesive palette with slightly reduced saturation. Use a warm off-white or beige tone as the background color for the lower section. Reserve the darkest tones for a few visual focal points, and retain one accent color that echoes the original photograph.

Keep all geometric edges crisp and sharp. Add only an extremely subtle printed grain texture within the color blocks, with slight registration misalignment allowed on a few edges. Do not render the entire image with rough paper texture or glitch-art effects.

TEXT
Add a small amount of archival-style typography to the lower section: automatically generate a short English title based on the content of the photo, accompanied by the small number NO. 023. Place the title in an area of negative space where it does not obstruct the subject, and position the number diagonally opposite the title to create visual balance.

Do not fabricate real locations, dates, identities, or events, and do not add dense explanatory text. The overall composition should resemble a page from a contemporary art book: a rich, realistic photograph on top paired with a bold, highly simplified, orderly geometric interpretation beneath it.

FINAL AESTHETIC
Restrained, gentle, distinctive, contemporary art book, realistic photography paired with crisp geometric abstraction.

AVOID
Exact real-person likeness, celebrity identity, cartoon-like faces, 3D effects, plastic materials, clashing neon colors, random doodles, full-frame illustration, arrows, labels, borders, watermarks, logos, dense text.
