Titanium Smartphone Triptych

Goal: Create a premium editorial comparison triptych of three flagship titanium smartphones side by side, photographed from the rear at matching three-quarter angles, like a luxury tech magazine ad. Canvas: Wide 16:9 horizontal composition, dark charcoal-to-black gradient studio background, subtle smoky texture, glossy reflective floor line at the bottom, dramatic rim lighting and soft bloom. Layout: Place a huge thin uppercase headline centered at the top reading {argument name="headline text" default="TITANIUM"}. Directly below it, add the subtitle {argument name="subtitle text" default="Three brands. One metal. Zero agreement."}. Put a small black rounded rectangle badge in the upper-right corner with bold white text {argument name="badge text" default="GPT"}. Center the three phones across the lower two-thirds with equal spacing and identical visual scale. Subject details: Show exactly 3 smartphones. Left phone: iPhone 16 Pro in Natural Titanium, warm champagne/gold body, rear Apple logo, three large camera lenses in a square camera island, warm gold accent lighting around the edges. Center phone: Samsung Galaxy S24 Ultra in Titanium Gray, dark gray rectangular slab with squared corners, rear Samsung logo, five separate rear camera/sensor circles, electric blue rim light along the right edge. Right phone: Google Pixel 9 Pro in Obsidian black, rear Google G logo, horizontal black camera bar with lenses and flash, green accent rim light along the side. Visible labels: Include exactly 3 product label groups near the phones. Left label reads "Apple iPhone 16 Pro" on the first line and "Natural Titanium" on the second line. Center label reads "SAMSUNG" on the first line, "Galaxy S24 Ultra" on the second line, and "Titanium Gray" on the third line. Right label reads "Google" on the first line, "Pixel 9 Pro" on the second line, and "Obsidian" on the third line. Add a small creator handle centered at the bottom reading {argument name="creator handle" default="@TechWithYami"}. Visual style: Ultra-realistic 3D product render, premium editorial lighting, metallic surfaces, soft reflections, crisp lens glass, shallow studio haze, high contrast, cinematic color accents: gold left, blue center, green right. Constraints: Use exactly three phones and exactly three product label groups; keep all text clean, legible, and minimal; no extra devices, hands, people, charts, or clutter.
