Cinematic Spartan Helmet Poster

Create a vertical, cinematic-style historical poster with the theme of{argument name="ancient city" default="SPARTA"} The design employs a dark, minimalist composition, with a background of textured parchment in deep burgundy and black, featuring subtle shadow effects and a rough, grainy film texture. A large title line is placed at the top center.{argument name="headline text" default="SPARTA"} Uses wide-spaced, elegant ivory-colored Roman serif capital letters. Add a small subheading directly below it.{argument name="subtitle text" default="LACONIA · PELOPONNESE"} The text uses micro-spaced capital letters with centered dot separators. Below, in the center, is displayed an ancient Spartan bronze Corinthian helmet, weathered and rust-red, facing forward with black hollow eye sockets, a narrow nose guard, and worn metal edges with highlights, topped with a tall, deep red horsehair. The helmet is placed in dramatic, low-key lighting, casting a long, dark shadow to the lower right. At the very bottom, a line of ivory-colored, small italicized text is added.{argument name="tagline" default="Explore with Visionaria — the first Cinematic Imagination App"} Maintaining a clean and symmetrical design, a large negative space is left between the title and the helmet, and the image contains no figures, extra objects, logos, or modern elements. It adopts a sophisticated ancient historical film poster style, using somber chiaroscuro lighting to present realistic textures, and employs a 2:3 vertical poster ratio.
