Theme: Vertical 3:4 science infographic showing the life cycle of banana through green, ripe, spotted, overripe as one continuous food object.
Subject: One complete banana stays structurally connected from end to end, with each time-slice segment showing a different stage rather than separate foods placed side by side.
Scene: Light beige educational infographic surface with clean science-card polish; sugar, texture, aroma, cooking advice are shown as observable color, texture, moisture, sprouting, wrinkling, or decay changes on the same food body.
Composition: Fixed vertical 3:4 layout: top title area, centered horizontal food silhouette, four to six evenly divided time-slice sections from early condition to spoiled condition, clear separators, and compact notes around each segment.
Signature elements: Single-object continuity, horizontal time-slice divisions, stage labels for green, ripe, spotted, overripe, realistic stage detail from sugar, texture, aroma, cooking advice, and a top title naming the life of banana.
Style: High-realism food-science infographic with Xiaohongshu-style clarity, realistic surface texture, clean cut-line rhythm, gentle shadows, and collectible educational-card finish.
Color palette: Warm light beige background, natural food colors that shift by stage, restrained annotation accents, crisp dark readable text, and small warning or check marks where useful.
Lighting: Soft even studio light with subtle shadows that reveal food texture, moisture, wrinkles, sprouts, and spoiled details without making the graphic messy.
Typography: Chinese infographic labels appear as short stage names, appearance notes, internal-change notes, and eating advice labels; all text stays brief, legible, and placed close to the relevant slice.
Restrictions: Clean focused visual treatment with coherent detail and source-consistent structure.
