Superposition narrative de réalité encrée

Transform the input photo into a before-and-after comparison poster. Keep the top approximately 40%-48% as the same original photo with authentic photographic texture, perspective, subject count, character poses, landmark outlines, and natural lighting, without cropping out key facts; the bottom approximately 52%-60% still uses the same scene and perspective, but adds a light hand-drawn storybook illustration layer. Use slightly hand-trembled deep ink black thick lines to outline traceable buildings, roads, landscapes, people, or objects in the photo, and select 1-3 suitable story characters or props from the photo's semantics, such as a walking small animal, paper airplane, flowers, flags, camera, luggage, fish, or balloons. They must stand on rooftops, bridge railings, mountain ridges, tabletops, or roadside, with correct perspective, occlusion relationships, and contact shadows; edges may overstep by about 5%-18%. Photo facts account for about 65%-80% of the frame, and the hand-drawn layer about 20%-35%. The hand-drawn part uses 4-7 distinct flat colors extracted from the photo and 1-2 highlight accent colors, retaining slight paper fiber and print grain; the real photo keeps natural texture. Preserve at least 12% of continuous low-information area, and do not add large titles. Unless already present in the original image, do not generate text, brands, logos, QR codes, signatures, watermarks, or corner marks. Do not cartoonify the entire photo, and avoid crayon, watercolor, 3D plastic, neon gradients, or random sticker overlays.
