Samsung Galaxy S26 Ultra Poster

for{argument name="product name" default="Samsung Galaxy S26 Ultra"} Design a high-end commercial advertising poster with a stylish and modern Samsung flagship style. Use a vertical poster canvas with a deep, futuristic navy black background, complemented by a soft gradient effect, delicate blue and silver halos, glossy reflections, and high-end studio lighting. Place the white SAMSUNG logo in the upper left corner. In the center, place the prominent headline "Galaxy S26 Ultra," below which is a smaller, glowing blue subheading "The Latest AI Phone," and the slogan "Power. Precision. Intelligence." at the bottom. In the center of the image, showcase two high-end silver smartphones: the left phone shows the back with a matte silver finish and five clearly visible camera/sensor circles in the upper left corner; the right phone shows the front screen with extremely narrow bezels, a centered punch-hole camera, and an wallpaper featuring abstract metallic geometric patterns in silver, black, and lavender tones. A silver S Pen is placed diagonally on the left side of the phone. Add a glowing blue semi-circle halo and a horizontal halo at the bottom of the device, reflecting the phone onto a polished surface. In the lower third of the poster, a clean specifications bar is designed, containing six features in two rows and three columns, separated by thin vertical lines and minimalist outline icons: 1) Phone icon with "6.9-inch Dynamic AMOLED display", 2) Camera icon with "200MP professional-grade camera", 3) Chip icon with "Snapdragon® 8 Elite Gen 5 for Galaxy", 4) Stylus icon with "Built-in S Pen", 5) Battery icon with "5000mAh battery", 6) Shield/lock icon with "Privacy display". At the bottom center, the call to action "Available Now" and the supporting text "Galaxy AI, Born for Your Everyday Life" are added, accompanied by two small flashing symbols. A clean white and light blue font is used, centered, with high-end spacing, presenting a realistic product rendering and metallic edges, without any additional text or watermarks.
