Create a photo-realistic advanced [Product Category] promotional poster with a 4:5 aspect ratio. It is designed as a clean global out-of-home (OOH), digital, and social media promotional layout, featuring strict grid alignment, advanced whitespace, and precise typography. The poster idea is "[Promotional Slogan]", but please do not present this phrase as visible text.

A strict 12-column poster grid with 6% margin is used. Keep all text aligned with this grid. The image is divided into four layers: background shape, giant background layout, subject/product photography, and neat graphic text overlay.

Background: Pure matte white canvas. A large rounded rectangular block is placed behind the main body, occupying about 70% of the poster's height and 76% of its width, centered and slightly above the center. This color block uses a controlled [Brand Main Tone] gradient, gently glowing from the top left to the bottom right. At the back of the main body and product, a giant cropped typesetting is placed, with the content "[Background Hero Words]", using ultra-bold geometric sans-serif font. The word serves only as a background layer: huge, cropped by the edge of the frame, wide spacing, a [brand main tone] darker than the rectangular block, with subtle embossed depth, soft shading, and low enough contrast not to interfere with the product.

Subject and product: [Describe the model or subject — for example, "a female model with a neat editorial style, a neutral confident expression, a natural breeze blowing her hair, a soft off-white outfit, and a [accent color] jacket"]. Shot from a slightly low hero angle. The body leans to add depth, the face turns toward the viewer, and direct eye contact occurs. One hand reaches toward the camera, holding the product shown in the reference image uploaded. The product is the dominant object in the front, slightly tilted to showcase [key product details—for example, the "triple-camera system, sandblasted titanium edges, and a centrally centered brand logo"]. Maintain product clarity with realistic surface reflections, material textures, fine details, and soft halos around advanced features. Keep the faces of the models behind them clearly visible.

Light and shadow: soft studio main light from the left front, warm contour light from the right, and subtle [brand main color tone] reflective light from background color blocks. The skin remains natural and untouched, with a genuine gaze. The product edges have clear [material finishes—for example, "metal/matte/polished"] highlights. The shadows are soft and controlled.

Typography Overlay: All text must be flat, clear, and perfectly aligned graphic layouts—not drawn within the scene. Accurately render the following text elements once; do not add extra text:

Top left, black small logo: [Brand Logo Name/Icon]

In the top right corner, sans-serif font: "[Brand subslogan — for example, 'Born for Apple Intelligence.' ’]”

Center left, glass mimicry capsule: "[Product name — for example, 'iPhone 17 Pro']"

Large background text: "[Background Hero Words]"

Lower right main text, clear small sans serific font:
"[Product Name]. [Strong statement — in a word. ]
[Function 1]. [Function 2].
[Conclusion — for example, 'Designed for the future.] ’]”

Bottom functional band: Place four glass white rounded corner cards of equal width along the bottom, aligned with the grid, at the same height, spaced at the same interval, and aligned with the baseline. Each card has a minimalist line icon above the title. Accurate rendering:
Card 1: "[Feature Title 1]" / "[Function Title 1]"
Card 2: "[Feature Title 2]" / "[Function Title 2]"
Card 3: "[Feature Title 3]" / "[Function Subtitle 3]"
Card 4: "[Feature Title 4]" / "[Function Title 4]"

Graphic details: Only two or three tiny flashing icons, fine graininess, soft glass mimicry, controlled [brand main tone]-white-[accent colors] palette, no neon, no oversaturation.
