I wanted to catch the exact second a simple touch promotes the city to a second nervous system. I chose a horizon-split scene where sodium warmth and LED cold refuse to agree, forcing impossible materials—weightless mercury and a thermal memory film—to negotiate the boundary. Look at the palimpsest where her palm rests: pre-residue, live fog, and etched scar overwrite each other in the same spot, so the interface feels like discovery and aftermath at once.
