目标：为 {argument name="brand name" default="UtopikAI Studio"} 创建一款简洁的单色品牌指南封面，将其呈现为高端 AI 工作室的视觉识别系统。
画布：1:1 正方形比例，炭黑色背景，带有细腻的颗粒感、微弱的暗角以及细致的工程绘图线条。采用极简的未来主义编辑排版，并留有充足的负空间。
布局：在靠近画布边缘处添加极细的矩形边框，带有微小的边角刻度；在顶部中心、左侧中部、右侧中部和底部中心添加小型十字准星标记；在两侧边缘附近添加淡淡的垂直虚线引导线。左上角放置小型间距大写文本“UTOPIKAI STUDIO”；右上角放置“BRAND GUIDELINES”。中心处构建一个大型几何结构网格：一个 2x2 的正方形网格，包含淡淡的圆弧片段和四分之一圆曲线，类似于 Logo 结构辅助线。将主 Logo 组合置于此网格的中下部。
Logo 组合：左侧使用一个白色抽象图标，由四个包含四分之一圆切口的方块组成，形成一个对称的现代标志。右侧设置字标“UtopikAI”，采用加粗、清晰的几何无衬线字体，呈亮白色；“Studio”字样较小且较细，对齐在字标右下方。总计 2 个 Logo 元素：1 个抽象图标和 1 个双行字标。
主标题区域：在左下象限，放置大标题 {argument name="document title" default="Brand Kit"}，使用白色、清晰的现代无衬线字体。在其正下方，添加副标题 {argument name="subtitle text" default="Visual identity system"}，使用较小的柔和灰色文本。在副标题下方，添加一条短细的白色水平线和一条较长的极淡灰色线条。
页脚：沿底部边缘添加小型技术性页脚标签：左侧为“VERSION 1.0”，中间为“VISUAL IDENTITY SYSTEM”，右侧为 {argument name="year" default="2024"}。用细长的角度绘图线和微妙的水平线连接页脚区域。
视觉风格：高端黑白品牌手册封面，极简主义，科技奢华感，精准的瑞士网格设计，高对比度白色排版，微妙的灰色结构线，清晰的矢量渲染效果，无样机透视。
约束：使用 5 组主要文本：左上角工作室标签、右上角指南标签、中心 Logo 组合、左下角标题/副标题块以及底部页脚元数据。保持所有文本清晰易读。避免使用额外的颜色、照片、人物、阴影或装饰性杂物。
英文提示词
Goal: Create a sleek monochrome brand guidelines cover for {argument name="brand name" default="UtopikAI Studio"}, presenting it as a premium AI studio visual identity system.
Canvas: Square 1:1 format, black charcoal background with subtle grain, faint vignette, and thin technical drafting lines. Use a minimal futuristic editorial layout with generous negative space.
Layout: Add a very thin rectangular border close to the canvas edges, with tiny corner ticks, small crosshair marks at the top center, left middle, right middle, and bottom center, and faint dotted vertical guide marks near both side edges. In the upper left, place small spaced uppercase text “UTOPIKAI STUDIO”; in the upper right, place “BRAND GUIDELINES”. In the center, build a large geometric construction grid: a 2-by-2 square grid with faint circular arc segments and quarter-circle curves, like logo construction guides. Overlay the main logo lockup across the middle-lower portion of this grid.
Logo lockup: Use a white abstract icon to the left, made from four square tiles containing curved quarter-circle cutouts, forming a symmetrical modern mark. To the right, set the wordmark “UtopikAI” in bold clean geometric sans serif, bright white, with “Studio” smaller and lighter aligned under the right side of the wordmark. Count exactly 2 logo elements: 1 abstract icon and 1 two-line wordmark.
Main title area: In the lower left quadrant, place the large title {argument name="document title" default="Brand Kit"} in white, set in a clean modern sans serif. Directly beneath it, add the subtitle {argument name="subtitle text" default="Visual identity system"} in smaller muted gray text. Under the subtitle, add one short thin horizontal white line and one longer very faint gray line.
Footer: Along the bottom edge, add small technical footer labels: left “VERSION 1.0”, center “VISUAL IDENTITY SYSTEM”, and right {argument name="year" default="2024"}. Connect the footer area with thin angular drafting lines and subtle horizontal rules.
Visual style: Premium black-and-white brand kit cover, minimalist, tech-luxury, precise Swiss grid design, high contrast white typography, subtle gray construction lines, crisp vector-like rendering, no mockup perspective.
Constraints: Use exactly 5 main text groups: top-left studio label, top-right guidelines label, central logo lockup, lower-left title/subtitle block, and bottom footer metadata. Keep all text sharp and legible. Avoid extra colors, photos, people, shadows, or decorative clutter.
