科普图表：可可豆蜕变记

Infographic poster documenting the chocolate production process from cocoa bean to finished bar, front-view flat presentation. Layout: a horizontal six-stage flowchart running left to right across the full width: harvest (cracked cocoa pods), fermentation (5-7 days in banana-leaf-lined boxes), drying in the sun (one week), roasting at 120-150°C, grinding into cocoa liquor and pressing into cocoa butter and powder, then conching and tempering to form the finished bar. Each stage sits in a rounded card with a flat icon, a one-line description, and a temperature or duration data badge. A thin progress arrow with gradient color connects the stages. Color system: rich chocolate browns (#4E2A17, #6F3E1F), cacao gold (#D4A017), cream (#F7F0E3) and a red accent (#C0392B) for the final bar stage. Typography: bold condensed sans-serif titles, medium descriptions, small data captions. Background: subtle cocoa-powder speckle texture with a soft warm vignette. Data feel: artisan factory guide with precision temperature and time labels. Lighting: warm diffused light from the upper right, soft shadows under cards, appetizing matte finish. 4k
