生成一张 16:9 横版主题活动海报，画面必须是高完成度的平面设计作品，而不是普通宣传插画。

【核心主题】
活动主题：[活动主题]
活动名称：[活动名称]
副标题：[活动副标题 / 主题语]
时间：[日期与时间]
地点：[地点]
主办方：[主办机构]
补充信息：[报名方式 / 网站 / 二维码占位 / 嘉宾信息，可为空]

【整体视觉气质】
清楚、克制、潮湿、冷静、图形化、低噪声、高明度、强设计感。
画面像一张印刷完成的活动海报，又像隔着一层湿润透明介质被重新观看。
整体不能像商业科技模板、不能像普通活动背景板、不能像复杂插画。

【画面结构】
采用严格的 16:9 横版构图。
画面内部由一条强轴线组织视觉阅读路径，轴线可以是偏左垂直轴、轻微斜向轴或横向测量轴，但必须清晰。
中部形成最密集的主题识别核心，主体边缘、下部或侧边被画幅裁断，保留画外延展感。
不要使用竖版海报构图，不要使用中心对称广告构图，不要平均铺满画面。

【主体处理】
将活动主题转译为一个低细节、高识别的抽象主体。
主体不能完整写实呈现，而要被压缩成：
1. 暗色骨架
2. 负形空洞
3. 局部识别边缘
4. 少量低明度质量块
5. 断续轮廓方向
6. 被裁切的结构片段

主体必须像从大面积高明度主场内部显影出来，而不是贴在背景上。
主体边缘必须被透明介质切过，形成轻微断续、弯折、漂浮、遮挡、折射和被吞没的感觉。
主体细节保持低密度，只保留主题识别所需的最少结构信息。

【场域与背景】
背景不是装饰纹理，而是由活动主题自身推导出的可见介质场。
建立一个大面积高明度、低噪声的主场，占画面面积的 70% 到 82%。
主场必须穿过主体、文字和空白区域，形成统一的空间层。

背景介质包含：
- 透明覆盖层
- 湿润表面反射
- 青白色轻高光
- 轻微扫描颗粒
- 柔和细折痕
- 不同尺度的场域扰动
- 局部折射弧线
- 被软化的暗色边缘

这些扰动必须跨越主体、文字和空白，不允许只停留在背景上。

【色彩比例】
使用严格的色彩层级：
- 高明度主色：70% 到 82%，用于主场
- 低明度结构色：10% 到 18%，用于主体、细线、标签、骨架
- 透明轻高光：3% 到 7%，用于介质弧线、折射、湿润反光
- 高能注记色：小于 1%，全画面只能出现一次

高能色只能用于一个关键小信息节点，例如一个微小圈注、短线轨迹、定位点或时间标记。
高能色不能扩散成装饰系统，不能出现多个强调点。

【文字系统】
加入活动海报必要信息，但文字必须克制、技术感、无衬线、小尺度、宽字距。
文字像坐标、索引、年份、边界标签、测量标记，而不是商业广告大标题。
文字与图像处于同一空间层，必须被主场和透明介质轻微压住，不能漂浮在最上层。

文字内容只允许使用以下信息，不生成额外乱码文字：
- [活动名称]
- [活动副标题 / 主题语]
- [日期与时间]
- [地点]
- [主办机构]
- [报名方式 / 网站 / 二维码占位 / 嘉宾信息]

排版规则：
主标题高度控制在画面高度的 6% 到 9%。
辅助文字高度控制在画面高度的 1.2% 到 2.5%。
文字集中贴近强轴线、边界线或底部信息带。
可以加入少量细线、编号、刻度、年份、坐标符号。
如果模型无法准确生成可读文字，则保留干净的文字排版占位区，不要生成伪文字、乱码或无意义字符。

【信息节点】
在一个关键小信息节点放入唯一的高能色注记。
该节点可以靠近日期、入口、主题核心边缘或画面轴线交叉点。
面积必须小于全画面 1%，像一次精确标记，而不是视觉装饰。

【材质与完成度】
画面具有平面印刷质感，但被湿润透明表面重新观看。
保留轻微扫描颗粒、细折痕、柔和青白高光、低噪声纸面质感、透明压层和折射边缘。
暗色结构边缘被介质软化，高光不能抢夺主体层级。
整体干净、冷静、留白充足、图形秩序明确。

【禁止项】
禁止完整写实主体。
禁止复杂插画细节。
禁止普通活动背景板。
禁止霓虹科技模板。
禁止大面积高饱和渐变。
禁止装饰性花纹背景。
禁止多个高能色注记。
禁止文字过大。
禁止无意义乱码文字。
禁止把背景做成独立装饰纹理。
禁止主体压在背景上。
禁止画面脏乱、拥挤、过度炫技。

【最终质量标准】
输出必须像同一位高级视觉设计师完成的横版主题活动海报。
画面应满足：
1. 16:9 横版明确
2. 强轴线明确
3. 主场面积大
4. 主体低细节但可识别
5. 介质穿过主体与文字
6. 文字克制、清晰、信息化
7. 只有一个高能色记忆点
8. 整体清楚、潮湿、冷静、图形化、高完成度

Generate a 16:9 horizontal theme event poster, the picture must be a high-completion-level graphic design work, not an ordinary promotional illustration. 【Core Theme】 Event theme: [Event theme] Event name: [Event name] Subtitle: [Event subtitle / theme slogan] Time: [Date and time] Location: [Venue] Organizer: [Organizing institution] Additional information: [Registration method / website / QR code placeholder / guest information, can be empty] 【Overall Visual Quality】 Clear, restrained, moist, calm, graphic, low-noise, high-brightness, strong design sense. The picture looks like a completed printed event poster, as if being viewed again through a wet transparent surface. Overall cannot look like commercial tech templates, cannot look like ordinary event backdrops, cannot look like complex illustrations. 【Picture Structure】 Use strict 16:9 horizontal composition. The interior of the picture is organized by a strong axis for visual reading path; the axis can be a偏左 vertical axis, slightly slanted axis, or horizontal measurement axis, but must be clear. The middle forms the densest theme recognition core, subject edges, lower part, or sides are cropped by the frame, retaining the sense of extension beyond the frame. Do not use vertical poster composition, do not use center-symmetric advertisement composition, do not evenly fill the picture. 【Subject Processing】 Translate the event theme into a low-detail, high-recognition abstract subject. The subject cannot be presented completely realistically, but must be compressed into: 1. Dark skeleton 2. Negative voids 3. Local recognizable edges 4. A few low-brightness mass blocks 5. Discontinuous outline directions 6. Cropped structural fragments The subject must appear as if developing from within a large high-brightness main field, not pasted on the background. Subject edges must be cut through by a transparent medium, forming slight discontinuity, bending, floating, blocking, refraction, and being swallowed feelings. Subject details maintain low density, keeping only the minimum structural information needed for theme recognition. 【Field and Background】 The background is not decorative texture, but a visible medium field derived from the event theme itself. Establish a large-area high-brightness, low-noise main field, occupying 70% to 82% of the picture area. The main field must pass through the subject, text, and blank areas, forming a unified spatial layer. Background medium includes: - Transparent overlay layer - Moist surface reflection - Cyan-white light highlights - Slight scanning grain - Soft fine creases - Field disturbances of different scales - Local refraction curves - Dark edges softened by the medium These disturbances must cross over the subject, text, and blank spaces, not allowed to stay only on the background. 【Color Proportions】 Use strict color hierarchy: - High-brightness main color: 70% to 82%, for the main field - Low-brightness structural color: 10% to 18%, for subject, thin lines, labels, skeleton - Transparent light highlights: 3% to 7%, for medium curves, refraction, moist reflection - High-energy annotation color: less than 1%, can only appear once in the whole picture High-energy color can only be used for one key small information node, such as a tiny annotation, short track, positioning point, or time marker. High-energy color cannot spread into a decorative system, cannot appear multiple emphasis points. 【Text System】 Add necessary event poster information, but text must be restrained, technical, sans-serif, small scale, wide character spacing. Text is like coordinates, indexes, years, boundary labels, measurement marks, not commercial advertisement big headlines. Text is on the same spatial layer as the image, must be slightly pressed by the main field and transparent medium, cannot float on the top layer. Text content can only use the following information, do not generate extra garbled text: - [Event name] - [Event subtitle / theme slogan] - [Date and time] - [Venue] - [Organizing institution] - [Registration method / website / QR code placeholder / guest information] Layout rules: Main title height controlled at 6% to 9% of picture height. Auxiliary text height controlled at 1.2% to 2.5% of picture height. Text concentrated close to the strong axis, boundary lines, or bottom information band. Can add a few thin lines, numbers, scales, years, coordinate symbols. If the model cannot accurately generate readable text, keep clean text layout placeholder areas, do not generate pseudo-text, garbled text, or meaningless characters. 【Information Node】 Place a single high-energy color annotation at one key small information node. This node can be near the date, entrance, theme core edge, or picture axis intersection point. Area must be less than 1% of the whole picture, like a precise mark, not visual decoration. 【Material and Completion】 The picture has平面印刷 texture, but is viewed again through a wet transparent surface. Retain slight scanning grain, fine creases, soft cyan-white highlights, low-noise paper texture, transparent lamination and refracted edges. Dark structure edges softened by the medium, highlights cannot seize subject hierarchy. Overall clean, calm, ample white space, clear graphic order. 【Prohibitions】 Prohibit complete realistic subject. Prohibit complex illustration details. Prohibit ordinary event backdrop. Prohibit neon tech template. Prohibit large-area high-saturation gradients. Prohibit decorative pattern background. Prohibit multiple high-energy color annotations. Prohibit oversized text. Prohibit meaningless garbled text. Prohibit making background into independent decorative texture. Prohibit subject pasted on background. Prohibit picture dirty, crowded, overly showy. 【Final Quality Standard】 Output must look like a horizontal event poster completed by the same senior visual designer. The picture should satisfy: 1. 16:9 horizontal clear 2. Strong axis clear 3. Main field area large 4. Subject low detail but recognizable 5. Medium passes through subject and text 6. Text restrained, clear, informative 7. Only one high-energy memory point 8. Overall clear, moist, calm, graphic, high completion Style keywords: high-key graphic poster, restrained editorial design, translucent wet surface, abstract dark structural silhouette, negative space, low-noise field, technical sans-serif typography, micro annotation, print texture, cyan-white highlights, cinematic flat composition, premium event visual identity
