Prompt
Create a vertical anime light-novel / manga poster cover for {argument name="story title" default="眠気屋の小瓶"}, with a dark midnight-blue fantasy atmosphere and luminous gold typography. Canvas is a tall 2:3 poster, dense cinematic composition, highly detailed Japanese illustration style, dramatic rim lighting, glowing particles, floating manuscript pages, ink splatters, and magical starry effects. At the very top, place the huge ornate Japanese title {argument name="large title text" default="眠気屋の小瓶"} in bright ivory-gold calligraphy with a soft glow, decorative crescent moon, filigree swirls, tiny stars, and an arched celestial ornament above it. Directly below the title, add the smaller subtitle {argument name="subtitle text" default="眠気を売りすぎた漫画家"} in clean pale lettering. Center of the poster: a transparent glass corked bottle floating upright, filled with a swirling spiral galaxy of blue-white starlight, sparkling dust, and a radiant core. The bottle emits a strong cyan-white magical glow that lights all surrounding characters and papers. Foreground: a tired young male manga artist with messy black hair, pale skin, blue-gray eyes, and a loose white T-shirt reaches upward toward the glowing bottle with one hand; his expression is exhausted, awed, and desperate. Black ink splashes and manga tools frame the bottom edge. Right foreground: a beautiful heroine with long flowing dark hair, large blue eyes, and a soft hopeful expression reaches out through drifting pages. She wears a white-and-silver fantasy outfit with delicate armor-like details and a glowing chest highlight. Upper right: an elegant mysterious shopkeeper, an adult man with long brown hair, sharp tired eyes, and dark clothing, watches calmly from the shadows among shelves of bottles and papers. Upper left: show the entrance of a strange shop with warm interior light and a sign reading {argument name="shop sign text" default="眠気屋"}; in the doorway, include a small back-view silhouette of a hooded young man facing into the shop. Background details: include exactly four clusters of manga/manuscript imagery around the central bottle: one lower-left cluster of illustrated manga panels with multiple small characters, one mid-right cluster of fantasy character sketches, one upper-middle cluster of loose pages flying diagonally, and one bottom-edge cluster of inked manuscript sheets. Keep the scene packed but readable, with the glowing bottle as the focal point. Use no English text, no logo, no watermark, and preserve the Japanese text exactly as specified.
