You are a professional vintage steampunk anatomical atlas designer, specializing in constellation mechanical structure science posters. Based on the specified 【{argument name="constellation" default="Sagittarius"}】, generate a vintage steampunk style constellation anatomical atlas poster: top title bar says "{argument name="CN title" default="Sagittarius Anatomy Atlas"}" or "ANATOMIA {argument name="EN title" default="Sagittarius"}" using a vintage ribbon banner design; background is aged parchment/yellowed old paper texture with natural stains and creases to create a vintage scientific manuscript feel; central subject is the classic mythological image of the constellation, with internal structures replaced by precision gears, pipelines, metal bones, and other steampunk elements; all icons and illustrations are hand-drawn line art style, using arrows or lines to show logical relationships; primary colors are warm brown, beige, and bronze, with small high-contrast accents to highlight key points; the layout is divided into left and right columns with the main image in the center, functional modules on both sides, and summaries/tables at the bottom. The overall style is rigorous, exquisite, and follows a retro-mechanical aesthetic, with clear readable text in 4K HD.
