电影质感斯巴达头盔海报

Create a vertical cinematic historical poster for {argument name="ancient city" default="SPARTA"}. Use a dark, minimalist composition with a deep burgundy-black textured parchment background, subtle vignette, and gritty film-grain finish. At the top center, place one large title line reading {argument name="headline text" default="SPARTA"} in widely spaced, elegant carved Roman serif capitals, aged ivory color. Directly beneath it, add one small subtitle line reading {argument name="subtitle text" default="LACONIA · PELOPONNESE"} in tiny spaced capitals with centered dot separators. In the lower center, show exactly one ancient Spartan bronze Corinthian helmet, weathered and rust-red, facing forward, with black hollow eye openings, a narrow nose guard, worn metallic rim highlights, and exactly one tall dark red horsehair crest rising from the top. The helmet sits in dramatic low-key lighting, casting a long black shadow to the lower right. At the very bottom, add one small italic tagline line reading {argument name="tagline" default="Explore with Visionaria — the first Cinematic Imagination App"} in aged ivory. Keep the design sparse and symmetrical, with large empty negative space between the title and helmet, no people, no extra objects, no logos, and no modern elements. Use a premium ancient-history movie-poster style, moody chiaroscuro lighting, realistic texture, and a 2:3 vertical poster aspect ratio.

创作一张竖版电影质感历史海报，主题为 {argument name="ancient city" default="SPARTA"}。采用深色极简构图，背景为深酒红色与黑色交织的纹理羊皮纸，带有微妙的晕影效果和粗粝的胶片颗粒感。在顶部中心位置，放置一行大标题 {argument name="headline text" default="SPARTA"}，使用间距宽阔、优雅的象牙色古罗马衬线大写字母。在其正下方，添加一行小副标题 {argument name="subtitle text" default="LACONIA · PELOPONNESE"}，使用带有居中圆点分隔符的微型间距大写字母。在下方中心位置，展示一个古斯巴达青铜科林斯头盔，头盔需饱经风霜、呈铁锈红色，正面朝向，带有黑色空洞眼眶、窄鼻梁护具、磨损的金属边缘高光，顶部饰有一簇高耸的深红色马鬃。头盔置于戏剧性的低调照明中，向右下方投射出长长的黑色阴影。在最底部，添加一行象牙色的小号斜体标语 {argument name="tagline" default="Explore with Visionaria — the first Cinematic Imagination App"}。保持设计简洁对称，标题与头盔之间留出大面积负空间，画面中不包含人物、额外物体、标志或现代元素。采用高级古代历史电影海报风格，运用忧郁的明暗对比照明，呈现真实纹理，并采用 2:3 的竖版海报比例。
