Produce an evening smart-home demonstration in a fictional living room. Preserve the exact lamp, blind motor, wall control, and room geometry from the references. Show three causal beats only.

Beat 1: close view of an adult hand pressing the upper wall-control button once; the ceiling light smoothly dims from neutral white to 30 percent warm light. Beat 2: medium room view as the lower button is pressed; the existing blinds close evenly from their current position, with outdoor light reducing naturally. Beat 3: a small tabletop control is rotated clockwise; the floor lamp turns on and stops at the approved amber level. End on a wide room state matching the approved interaction map.

Camera cuts only after each input is visible. Sound intent: tactile clicks, quiet blind motor, room ambience, no voice assistant or claims. Keep button identity, hand anatomy, light direction, device count, cable placement, and state order stable. Avoid invented automation, surveillance implication, floating interfaces, brand logos, readable generated text, or watermark.
