Ceremonial Celebration Visual Poster

围绕主题生成一张带庆祝仪式感的主题视觉：主题对象以近距离主形体占据画面中下部，姿态安静、正面稳定，边缘允许被暗部轻微吞没，形成沉着的存在感；背景是克制的纯净空间，由主题情绪派生出底色与清晰的光照层次，一侧压入大块柔边椭圆暗影，另一侧保留较亮的呼吸区，让第一眼先看到被光切出的主形体，再顺着阴影和留白读到信息层。色彩从主题自身的材质、季节、身份与情绪中提取，保留大面积冷静干净的结构底色、少量温度明确的主体色、清晰高亮的信息色和深部阴影色的角色关系；整体保持清透安静、低饱和但不浑浊，明暗对比干净，暗色要有透明深度，亮色只用于核心受光面、发光标题和少量标记。顶部放极细、宽字距的小型信息文字，像远处的仪式刻度；中心上方放短促的主名或主题名，字体端正、有轻微庄重感。底部用一行巨大的标题作为情绪标题，笔画细长、连贯、带霓虹般的柔白外晕，大幅覆盖主形体下缘，与其下方较小的日期或辅助信息形成叠压关系。画面表面带轻微胶片颗粒、柔焦暗角和投影质感，信息密度低，空间留得很满，最终效果应像一张私密而正式的纪念影像，靠光影、克制色阶和大字的发光轨迹建立记忆点。

Create a thematic visual with a sense of celebration centered around theme: the subject occupies the lower-middle part of the frame with a close-up main form, maintaining a quiet and stable frontal posture, with edges allowed to be slightly swallowed by shadows for a composed presence. The background is a restrained pure space, with base color and clear lighting layers derived from the theme's mood; one side is pressed with a large soft-edged oval shadow, while the other retains a brighter breathing area. Colors are extracted from the material, season, and identity of the subject, maintaining a large area of clean structural base colors and clear highlight information colors. At the bottom, use a line of huge glowing title as an emotional heading with long, coherent strokes and a neon-like soft white halo. The surface features slight film grain and soft focus vignetting, resulting in a private and formal commemorative image built on light, shadow, and restrained color scales.
