Outpainting fluido per wallpaper 16:9

Zoom out and expand the reference photo into a 16:9 landscape aspect ratio. Seamlessly extend the environment and background scenery on the left and right sides, matching the original lighting, weather conditions, color grading, and texture. Logically complete any cropped or cut-off elements at the borders, such as branches, architecture, or silhouettes, ensuring realistic continuation. Keep the original central content completely intact without distortion.
