Generate a 16:9 landscape event poster. The image must be a highly polished piece of graphic design, not a generic promotional illustration. 【Core Theme】 Event Theme: [活动主题] Event Name: [活动名称] Subtitle: [活动副标题 / 主题语] Date/Time: [日期与时间] Location: [地点] Organizer: [主办机构] Supplementary Info: [报名方式 / 网站 / 二维码占位 / 嘉宾信息, can be empty] 【Overall Visual Tone】 Clear, restrained, moist, cool, graphic, low-noise, high-key, strong sense of design. The image should look like a printed event poster viewed through a layer of moist, transparent medium. The overall aesthetic must not resemble commercial tech templates, standard event backdrops, or complex illustrations. 【Composition】 Strict 16:9 landscape composition. The visual reading path is organized by a strong axis—either a vertical axis shifted to the left, a slight diagonal axis, or a horizontal measurement axis—which must be clearly defined. The core of the theme is concentrated in the center, with the edges of the subject, the bottom, or the sides cropped to suggest extension beyond the frame. Do not use vertical poster layouts, center-symmetric advertising layouts, or evenly filled compositions. 【Subject Treatment】 Translate the event theme into a low-detail, highly recognizable abstract subject. The subject should not be rendered realistically but compressed into: 1. Dark skeletal frames 2. Negative space voids 3. Partial recognizable edges 4. Minimal low-luminance mass blocks 5. Intermittent contour directions 6. Cropped structural fragments The subject must appear to emerge from within a large, high-key field rather than being pasted onto a background. Subject edges must be intersected by the transparent medium, creating a sense of slight intermittency, bending, floating, occlusion, refraction, and submersion. Subject details must remain low-density, retaining only the minimal structural information required for theme recognition. 【Field and Background】 The background is not a decorative texture but a visible medium field derived from the event theme itself. Establish a large-area, high-key, low-noise field occupying 70% to 82% of the frame. This field must pass through the subject, text, and empty areas, creating a unified spatial layer. Background medium includes: - Transparent overlay - Moist surface reflections - Cyan-white light highlights - Subtle scanning grain - Soft fine creases - Field disturbances of varying scales - Local refractive arcs - Softened dark edges These disturbances must span across the subject, text, and empty space; they must not be confined to the background. 【Color Ratio】 Strict color hierarchy: - High-key primary color: 70% to 82%, for the main field - Low-luminance structural color: 10% to 18%, for the subject, fine lines, labels, and skeletons - Transparent light highlights: 3% to 7%, for medium arcs, refraction, and moist reflections - High-energy accent color: Less than 1%, appearing only once in the entire frame The high-energy color must be used for only one critical small information node, such as a tiny circle, a short trajectory line, an anchor point, or a time marker. The high-energy color must not spread into a decorative system; multiple emphasis points are prohibited. 【Typography System】 Include necessary event information, but the text must be restrained, technical, sans-serif, small-scale, and wide-tracked. Text should resemble coordinates, indices, years, boundary labels, or measurement marks rather than commercial advertising headlines. Text and imagery occupy the same spatial layer and must be slightly suppressed by the main field and transparent medium; they must not float on the top layer. Only the following information is allowed; do not generate extra garbled text: - [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] Layout Rules: Main title height: 6% to 9% of frame height. Auxiliary text height: 1.2% to 2.5% of frame height. Text should be clustered near the strong axis, boundary lines, or the bottom information band. Small amounts of fine lines, numbering, scales, years, or coordinate symbols may be added. If the model cannot generate readable text accurately, leave clean placeholders for typography; do not generate pseudo-text, garbled characters, or meaningless symbols. 【Information Node】 Place the unique high-energy color annotation at one critical small information node. This node can be near the date, entrance, core theme edge, or the intersection of the visual axes. The area must be less than 1% of the total frame, acting as a precise marker rather than visual decoration. 【Material and Finish】 The image has a flat print texture but is viewed through a moist, transparent surface. Retain subtle scanning grain, fine creases, soft cyan-white highlights, low-noise paper texture, transparent laminations, and refractive edges. Dark structural edges are softened by the medium; highlights must not compete with the subject hierarchy. The overall look is clean, cool, with ample negative space and clear graphic order. 【Prohibitions】 No complete realistic subjects. No complex illustrative details. No generic event backdrops. No neon tech templates. No large-area high-saturation gradients. No decorative patterned backgrounds. No multiple high-energy color annotations. No oversized text. No meaningless garbled text. No background as an independent decorative texture. No subject pasted onto the background. No dirty, crowded, or overly flashy compositions. 【Final Quality Standards】 The output must look like a landscape event poster completed by a senior visual designer. The image must satisfy: 1. Clear 16:9 landscape format 2. Strong, clear axis 3. Large main field area 4. Low-detail but recognizable subject 5. Medium passing through subject and text 6. Restrained, clear, informative typography 7. Only one high-energy color memory point 8.
