A standard router in an adjacent property can silently map a neighbour's movements and physiological signals through walls without their knowledge.

Prompt: A cutaway view of two adjacent apartments sharing a wall, with a standard consumer Wi-Fi router in one apartment projecting invisible sensing waves through the wall into the neighbouring apartment, where an unaware person goes about daily life. A translucent overlay on the neighbouring apartment shows a detailed map of the occupant's movement path and a heart rate waveform, suggesting comprehensive monitoring from an unmodified-looking device next door. Style: Detailed digital illustration blending technical schematic linework with painterly atmospheric rendering, as if a scientific textbook were reimagined by a noir graphic novelist. Colour palette of deep midnight blue, charcoal black, and slate grey as foundations, accented with electric teal, bioluminescent green, and cold amber. Lighting is dramatic and directional, suggesting surveillance or laboratory environments — pools of cold light against deep shadow, with occasional glowing circuit-trace highlights. Compositions favour tight framing with layered depth: foreground technical detail dissolving into abstracted background geometry. Detail level is high but purposeful, prioritising legible structure over decorative complexity. Mood is clinical yet ominous, precise yet unsettling. No text, lettering, captions, logos, watermarks or borders unless it is a technical drawing.
