Create a vertical cinematic ancient-history poster for {argument name="ancient city name" default="BABYLON"}. Use a tall 2:3 portrait canvas with a dark emerald green and antique gold palette, aged parchment texture, subtle film grain, and a distressed vintage book-cover finish. Composition: centered at the top is exactly 1 gold crescent moon; behind it are faint circular astrological chart rings and barely visible cuneiform-like inscriptions filling the upper background. Below, place exactly 1 huge serif title in pale weathered gold, reading {argument name="title text" default="BABYLON"}, with monumental Roman-style letterforms and slight texture erosion. Under the title, add exactly 1 small tagline line in gold, reading {argument name="tagline text" default="Explore with Visionaria, First Cinematic Imagination App"}, separated from the title by a thin horizontal ornament line with a tiny diamond at the center. The lower half shows exactly 1 grand Babylonian ziggurat fortress rising in tiers, centered and symmetrical, with stairways, towers, arches, crenellations, and small palm trees on terraces, lit by green moonlit mist. Foreground includes exactly 2 large dark palm silhouettes framing the scene, one on the left and one on the right, plus a calm river or canal at the bottom reflecting green-gold light. Add a thin double-line gold border around all edges with worn corners, faint cuneiform texture along the side margins, and exactly 1 small winged Mesopotamian emblem centered at the bottom border. Visual style: epic mythic landmark poster, moody nocturnal atmosphere, ancient Mesopotamian grandeur, high detail, cinematic depth, softly glowing haze, no modern objects, no people, no extra text, no watermark.
