Bright Minimalist Poster with Linear Typography

Organize {argument name="subject content" default="arbitrary subject content"} into a bright and clean flat poster. At first glance, the order is established by large areas of white space, thin-lined large characters, and a low-level diffusion of theme-colored spray. The image maintains a high-brightness background like a blank piece of paper. The main text appears in an extremely thin, uniform linear skeleton similar to engineering drawings. The character spacing is sparse but the scale jumps significantly: a small number of oversized characters are close to the edges to form a pillar-like visual weight, multilingual titles or subtitles hang horizontally above, and partial theme characters are disassembled and enlarged, appearing like logos or path nodes. Place a fluorescent mist block derived from the theme at the lower middle. The color is extracted from the theme's clearest, highest-brightness, and slightly acidic supporting colors. The center is fuller, and the edges dissipate outwards with a large number of tiny spray dots, vertically trailing several semi-transparent smoke pillars, making the text look like it is floating in front and behind the mist rather than pressed against the pattern. The text color uses high-saturation warm tones or theme-contrast colors clearly separated from the mist color, with a restrained area, serving as the unified voice for titles, descriptions, symbols, and bottom contact information; small characters are grouped in short lines, leaving wide room to breathe without filling the white space. All graphics maintain the flatness and cleanliness of digital printing, with only the edges of the spray appearing grainy, leaky, and of uneven density, avoiding heavy shadows, photo textures, gradient decorations, and crowded layouts; the final effect should be like an open field of characters in experimental communication, quiet, eye-catching, and slightly unstable.

Each picture element: {argument name="subject" default="city"} + 2026-07-08 + {argument name="greeting" default="good morning quote greeting"} + 5 different forms of information points + rich compositional rhythm changes
1 city each time, each city has different color matching logic and compositional logic changes
A total of 10 cities, 10 images, generated in sequence
Note: Each image has a different compositional layout.

围绕{argument name="主题内容" default="任意主题内容"}组织成明亮洁净的平面海报，第一眼由大面积留白、细线大字和一团低位扩散的主题色喷雾共同建立秩序。画面保持空白纸面般的高明度底场，主要文字以极细、均匀、近似工程绘图的线性骨架出现，字距疏朗但尺度跳跃明显：少量超大字贴近边缘形成门柱般的视觉重量，多语标题或副标题横向悬在上方，局部主题字被拆开放大，像标识也像路径节点。中部偏下放置主题派生的荧光色雾块，颜色从主题中提取最清亮、最高明度、带轻微酸性感的支持色，中心较饱满，边缘由大量细小喷点向外消散，并垂直拖出数条半透明烟柱，让文字像漂浮在雾面前后而非压在图案上。文字色使用与雾色形成清晰分离的高饱和暖调或主题对照色，面积克制，承担标题、说明、符号和底部联系方式的统一声音；小字成短行分组，留出宽阔呼吸，不填满空白。所有图形都保持数字印刷的平整与干净，只让喷雾边缘出现颗粒化、漏喷和密度不均，避免厚重阴影、照片质感、渐变装饰和拥挤排版；最终效果应像实验传播中的开放字场，安静、醒目、轻微不稳定。
