Edit only the lighting and verified device states in Video 1. Keep the office architecture, furniture, window geometry, adult actor identity, wardrobe, posture, gestures, hand contacts, camera movement, lens, focus pulls, timing, crop, and every object unchanged.

Transform the exterior from overcast afternoon to the approved blue-hour view in Image 1. Dim the existing daylight gradually while keeping physically consistent window reflections and shadow directions. At the exact source moment when the actor presses the wall control, switch the two desk lamps from off to the warm state in Image 2; their light must affect nearby surfaces and the actor naturally. Keep the ceiling fixture off for the entire clip. End with the same composition and object positions as Video 1, now balanced between cool window light and warm desk lamps.

Preserve original dialogue, button click, room tone, and music. Do not move the sun visibly, change weather, add city landmarks, alter the interface, invent an energy-saving claim, change furniture, beautify the actor, add new light fixtures, reshape reflections, retime the press, or add text, logos, and watermark.
