创建一张照片级真实的高级 [产品类别] 宣传海报，纵横比为 4:5。将其设计为整洁的全球户外广告（OOH）、数字和社交媒体宣传布局，具有严格的网格对齐、高级留白和精确的排版。海报创意是“[宣传标语]”，但请勿将该短语呈现为可见文本。
使用严格的 12 列海报网格，外边距为 6%。保持所有文本与此网格对齐。图像分为四层：背景形状、巨型背景排版、主体/产品摄影以及整洁的图形文本叠加。
背景：纯磨砂白画布。在主体后方放置一个大的圆角矩形块，占据海报高度的约 70% 和宽度的 76%，居中且略高于中间。该色块使用受控的 [品牌主色调] 渐变，从左上角向右下角轻轻发光。在主体和产品后方，放置巨型裁剪排版，内容为“[背景英雄词]”，采用超粗几何无衬线字体。该单词仅作为背景层：巨大，被框架边缘部分裁剪，字间距宽，比矩形块颜色更深的 [品牌主色调]，带有微妙的浮雕深度、柔和阴影，且对比度足够低，不会干扰产品。
主体与产品：[描述模特或主体 —— 例如，“一位具有整洁社论风格、中性自信表情、自然微风吹动头发、柔和米白色装束和 [点缀色] 夹克的女性模特”]。采用略微低视角的英雄角度拍摄。身体倾斜以增加深度，脸部转向观众并直接进行眼神交流。一只手向摄像机伸出，握着上传参考图中的产品。产品是前景的主导对象，略微倾斜以展示 [关键产品细节 —— 例如，“三摄系统、喷砂钛金属边缘和居中的品牌标志”]。保持产品清晰，具有真实的表面反射、材料纹理、微小的细节以及高级功能周围的柔和光晕。保持其后方模特的脸部清晰可见。
光影：来自左前方的柔和演播室主灯，来自右侧的温暖轮廓光，以及来自背景色块的微妙 [品牌主色调] 反弹光。皮肤保持自然且未经磨皮处理，具有真实的眼神光。产品边缘具有清晰的 [材料饰面 —— 例如，“金属 / 磨砂 / 抛光”] 高光。阴影柔和且受控。
排版叠加：所有文本必须是扁平、清晰、完美对齐的图形排版 —— 而非绘制在场景中。准确渲染以下文本元素一次，不得添加额外文本：
左上角，黑色小标志：[品牌标志名称/图标]
右上角，细无衬线字体：“[品牌副标语 —— 例如，‘为 Apple Intelligence 而生。’]”
左中位置，玻璃拟态胶囊：“[产品名称 —— 例如，‘iPhone 17 Pro’]”
大型背景文字：“[背景英雄词]”
右下角正文，清晰的小号无衬线字体：
“[产品名称]。[强力声明 —— 一句话。]
[功能 1]。[功能 2]。
[结束语 —— 例如，‘为未来而设计。’]”
底部功能带：沿底部放置四个等宽的玻璃白圆角卡片，与网格对齐，高度相同，间距相同，基线对齐。每张卡片在标题上方有一个极简线条图标。准确渲染：
卡片 1：“[功能标题 1]” / “[功能副标题 1]”
卡片 2：“[功能标题 2]” / “[功能副标题 2]”
卡片 3：“[功能标题 3]” / “[功能副标题 3]”
卡片 4：“[功能标题 4]” / “[功能副标题 4]”
图形细节：仅有两个或三个微小的闪烁图标，细微颗粒感，柔和的玻璃拟态，受控的 [品牌主色调]-白色-[点缀色] 色板，无霓虹，无过度饱和。

Create a photorealistic premium [PRODUCT CATEGORY] campaign poster in a 4:5 vertical aspect ratio. Design it as a clean global OOH, digital, and social campaign layout with strict grid alignment, premium white space, and precise typography. The campaign idea is "[CAMPAIGN TAGLINE]," but do not render that phrase as visible text.
Use a strict 12-column poster grid with 6% outer margins. Keep all text aligned to this grid. The image has four layers: background shape, giant background typography, subject/product photography, and clean graphic text overlays.
BACKGROUND: Pure matte white canvas. Place one large rounded-rectangle block behind the subject, occupying roughly 70% of the poster height and 76% of the width, centered slightly above the middle. The block uses a controlled [PRIMARY BRAND COLOR] gradient, glowing gently from top-left to bottom-right. Behind the subject and product, place giant cropped typography reading "[BACKGROUND HERO WORD]" in ultra-bold geometric sans-serif letters. The word is a background layer only: huge, partially cropped by the frame edges, wide letter spacing, darker [PRIMARY BRAND COLOR] than the rectangle, subtle embossed depth, soft shadow, and low enough contrast that it does not fight the product.
SUBJECT AND PRODUCT: [DESCRIBE MODEL OR SUBJECT — e.g., "a female model with a clean editorial look, neutral confident expression, natural slightly wind-touched hair, muted off-white outfit, and [ACCENT COLOR] jacket"]. Shoot from a slightly low hero angle. Body angled for depth, face turned toward the viewer with direct eye contact. One hand extends toward the camera holding the product from the uploaded reference image. The product is the dominant foreground object, slightly tilted to reveal [KEY PRODUCT DETAIL — e.g., "the triple camera system, brushed titanium edges, and centered brand logo"]. Keep the product sharp with realistic surface reflections, material texture, faint micro-details, and soft bloom around premium features. Keep the model's face readable behind it.
LIGHTING: Soft studio key light from front-left, warm rim light from the right, and subtle [PRIMARY BRAND COLOR] bounce from the background block. Skin remains natural and non-airbrushed with realistic catchlights. Product edges have clean [MATERIAL FINISH — e.g., "metallic / matte / glossy"] highlights. Shadows are soft and controlled.
TYPOGRAPHY OVERLAY: All text must be flat, crisp, perfectly aligned graphic typography — not painted onto the scene. Render exactly these text elements once, with no extra text:
Top left, small black logo: [BRAND LOGO NAME/MARK]
Top right, thin sans-serif: "[BRAND SUB-TAGLINE — e.g., 'Built for Apple Intelligence.']"
Mid left, glassmorphism pill: "[PRODUCT NAME — e.g., 'iPhone 17 Pro']"
Large background type: "[BACKGROUND HERO WORD]"
Bottom right body copy, small clean sans-serif:
"[PRODUCT NAME]. [POWER STATEMENT — one sentence.]
[FEATURE 1]. [FEATURE 2].
[CLOSING LINE — e.g., 'Designed for what's next.']"
BOTTOM FEATURE STRIP: Place four equal-width glass-white rounded cards along the bottom, aligned to the grid, same height, same spacing, same baseline alignment. Each card has one minimal line icon above the heading. Render exactly:
Card 1: "[FEATURE HEADING 1]" / "[FEATURE SUBLINE 1]"
Card 2: "[FEATURE HEADING 2]" / "[FEATURE SUBLINE 2]"
Card 3: "[FEATURE HEADING 3]" / "[FEATURE SUBLINE 3]"
Card 4: "[FEATURE HEADING 4]" / "[FEATURE SUBLINE 4]"
GRAPHIC DETAILS: Two or three small sparkle icons only, subtle grain, soft glassmorphism, controlled [PRIMARY BRAND COLOR]-white-[ACCENT COLOR] palette, no neon, no oversaturation.
