A man enters from off frame left and crosses the sunlit office in a few unhurried strides. He sets a ceramic coffee mug down on the marble tabletop beside the stacked books and the small potted succulent, steam curling up through the low golden light. He pauses briefly, then walks toward the floor-to-ceiling glass and stops, silhouetted against the hazy skyline, looking out. Static locked-off camera, deep focus with the brass lamp anchoring the foreground; hard low sun raking in from frame right, long warm shadows crawling across the marble, gentle lens haze. 35mm film grain, natural cinematic realism, single continuous shot, no cuts. Sound: quiet footsteps on hard floor, the soft ceramic knock of the mug on marble, muffled city hum through glass.
