Create a vertical 4:5 (1080x1350) mixed-style visual: a bold comparison between a basic link-in-bio service and a professional website. Background: Split diagonal background — left half (#FAFAFA with slight warm tint) vs right half (#E8F0FE with blue tint). A sharp diagonal dividing line with a subtle glow #2563EB. Visual metaphor — Two Doors: Left door: A generic, slightly flimsy gray door with a cheap paper sign taped to it reading "Linktr.ee" in lowercase. The door has visible cracks. A small price tag dangling: "Free". Muted, flat lighting. Right door: A solid modern door with an engraved nameplate ".com" in #0F172A. The door has clean lines, a smart handle, and a subtle blue glow emanating from underneath. A small confident badge: "Professional". Warm spotlight from above. Between the doors: A floating scale/scorecard — like a judge's scoreboard. Left side shows a low faded gray score. Right side shows a high bright blue score with a subtle glow. Foreground element: Three small floating icons at the bottom — a shopping cart, a chart icon, and a search/magnifying glass — floating on the right side of the image. Style: Cinematic architectural visualization meets clean editorial illustration. Depth of field focusing on the right door. Soft volumetric light. Mood: confident, eye-opening, upgrade moment.
