科普图表：啤酒家族谱系

Infographic poster presenting a family tree of the world's beer styles, front-view flat presentation. Layout: a branching tree diagram rooted at the bottom center with the ale and lager yeast families as two main trunks: the ale branch (top-fermented) splitting into pale ale, IPA, stout, porter, wheat beer, Belgian wit and saison; the lager branch (bottom-fermented) splitting into pilsner, helles, bock, Vienna and Munich dunkel. Each style node is a rounded card with a flat beer-glass icon, origin country, alcohol-by-volume percentage and typical serving temperature, with branch lines whose thickness encodes historical lineage. Color system: golden amber (#F2B441), barley gold (#D9A441), chestnut brown (#8B5E3C), deep black stout (#2B2B2B) and cream foam white (#FFF8E7) on a warm tavern background (#F5EDE0). Typography: classic serif for style names, clean sans-serif data captions. Background: subtle barley-grain texture with faint hop-cone pattern. Data feel: brewing-reference chart with lineage branches and style statistics. Lighting: warm pub-light glow from the upper right, soft shadows, inviting amber tones. 4k
