根据【XXX主题】自动生成一张收藏版史诗叙事海报：巨大优雅的人物侧脸剪影作为外轮廓，剪影内部自动生长出最契合该主题的完整世界观、标志性场景、角色关系、象征符号、关键建筑、生物、道具与氛围。整体不是普通拼贴，而是高级的剪影轮廓填充式叙事合成，带有双重曝光式联想，但更偏电影海报与梦幻水彩插画融合风格；柔和空气透视，轻雾化过渡，纸张颗粒，边缘飞白与刷痕，大面积留白，版式克制高级，安静、宏大、神圣、怀旧、诗意、传说感强。风格、色彩、场景、材质全部根据主题自动适配，所有元素必须强绑定主题，一眼识别，不要杂乱，不要硬拼贴，不要模板化背景，不要廉价奇幻素材。画面中需自然加入专属签名“WHY”，作为海报设计的一部分，位置低调但清晰，可放在左下角、右下角或标题附近，风格需与整体版式统一，像收藏版海报的作者落款或设计签章；签名字体精致、克制、高级，不可过大，不可破坏主体构图，不可显得突兀廉价。

A collectible epic narrative poster is automatically generated based on 【XXX主题】: a huge and elegant character profile is used as the outer outline, and a complete world view, iconic scenes, character relationships, symbolic symbols, key buildings, creatures, props and atmosphere that best fit the theme are automatically grown inside the silhouette. The whole is not an ordinary collage, but an advanced silhouette outline filled narrative synthesis, with double exposure associations, but more of a fusion style of movie posters and dreamy watercolor illustrations; soft air perspective, light mist transition, paper particles, white edges and brush marks, large areas of white space, restrained and advanced format, quiet, grand, sacred, nostalgic, poetic, and legendary. Styles, colors, scenes, and materials are all automatically adapted according to the theme. All elements must be strongly bound to the theme and recognized at a glance. No clutter, no hard collage, no templated backgrounds, and no cheap fantasy materials. The exclusive signature “WHY” needs to be naturally added to the picture. As part of the poster design, the position should be low-key but clear. It can be placed in the lower left corner, lower right corner or near the title. The style must be unified with the overall layout, like the author's signature or design signature of the collector's edition poster; the signature font is exquisite, restrained and high-end, not too large, not destroying the main composition, and not appearing obtrusive and cheap.
