Change only the view through my window

Edit my uploaded user photo. Treat the person, their face, clothing, pose, furniture, window frame and interior light as locked source material. Replace only the scenery visible through [WINDOW] with [IMAGINED WORLD], at a scale and horizon that fit the photographed camera. Add subtle, plausible colour spill on the glass but do not repaint skin. Keep glass reflections and any existing curtain in their original positions. Return one believable photograph plus a short note identifying the edited window region. No duplicate person, impossible perspective, invented signage or facial beautification. If the subject's face must remain pixel-identical, mask it and composite the original pixels; a text prompt alone cannot guarantee that.
