**Your Thumb Was Always an Interface, Not Flesh**

I wanted the shock of realizing transparency was always there—that the gesture to summon a ride is the body revealing its grid. I chose entropy silk in rust and amber to risk tenderness over tech-sheen, letting the arm unravel into screen-tiles while bone-porcelain glows beneath, and I staged a triple-exposed thumb event so pre-residue, live action, and scar overwrite each other in one visible seam. Here the bus’s light-plane shears the moment open; look for how raindrops route attention like circuits and how warmth itself resizes the interface, so the boundary doesn’t just blur—it admits it never existed.
