Imperial Steampunk Library Poster

Goal: Create an ornate vertical steampunk anime poster for {argument name="location name" default="Imperial Central Library"}, presenting a grand fantasy library and its mascot character as if it were a worldbuilding location card. Canvas: Vertical 2:3 poster, richly detailed, warm sepia and brass palette, high-resolution anime illustration with cinematic depth and elaborate Victorian ornamentation. Add a thin black-and-bronze decorative border around the entire image with gears, compass-like circles, filigree corners, and fine mechanical linework. Main setting: A vast imperial library interior with towering bookshelves on both sides, dark polished wood, long perspective aisle, arched glass window glowing at the back, ladders, balcony rails, old lamps, stacked books, crates, trunks, and subtle dust motes in warm light. The atmosphere should feel like a grand central archive containing airship blueprints, alchemy tomes, and classical literature. Main character: In the front-left/center foreground, show one young anime librarian-witch girl with long {argument name="hair color" default="black hair with dark red inner highlights"}, pale skin, soft red eyes, small round glasses, and a calm confident smile. She wears a large black pointed witch hat with a red underside, leather straps, a brass clock face, and exposed gears on the hatband. Her outfit is a black Victorian steampunk dress with puff sleeves, white blouse front, red skirt panel, high collar, red gemstone brooch, leather belts, brass gear ornaments, and metallic gold forearm gauntlets. She holds one large ornate brown book against her chest with white-gloved hands. Discrete visible characters and machines: Include exactly 1 main witch-librarian girl and exactly 5 small steampunk automaton librarians. The 5 automatons are: 1 small partial automaton at the lower left near the aisle, 1 automaton in the mid-background beside stacked books, 1 automaton standing on the right near a tall stack of books, 1 automaton in the lower center pushing or standing beside wheeled crates, and 1 larger foreground automaton at the lower right with a top hat beside stacked books. Give the automatons round doll-like heads, brass mechanical bodies, gears, pipes, small arms, and black top hats. Title plaque: In the upper-right area, place a dark rectangular ornamental sign with gold trim and filigree. Large Japanese title text: 「帝都大図書館」. Beneath it, smaller English subtitle: “Imperial Central Library”. Use elegant serif lettering in gold. Bottom caption panel: Add a dark ornate information plaque across the bottom with gold border and gear decorations. Include Japanese text on two lines: 「中心街にある大図書館。飛行船の設計図から錬金術書、文学まで揃っている。」 Beneath it, include the English translation in small serif type: “A grand library located in the Central Block. It houses everything from airship blueprints and alchemy tomes to classical literature.” Visual style: Detailed Japanese anime character art blended with realistic fantasy background painting, steampunk brass mechanics, intricate gears, warm backlighting, polished wood reflections, elegant poster composition, premium collectible card feel. Constraints: Keep all visible text sharp and legible, do not add extra characters beyond the exact counts, avoid modern technology, avoid sci-fi neon, avoid watermark or logo, maintain a balanced composition with the character in the foreground and the library aisle receding behind her.
