Where the Rail Splits Skin from Signal

I wanted to catch the exact breath-held instant when device and body stop pretending to be separate. I split the carriage at the window rail: below, packed commuters and smeared plastics; above, their embedded “singing crystal” revealed as a refractive sky that harmonizes their veins in Fibonacci intervals. I chose prismatic palms, bio-copper capillaries, and chrome turning to skin where hands grip — so the exhilaration feels like suddenly seeing ultraviolet, a boundary loosening until you realize it was yours to widen all along.
