At the tournament, the S20’s light made him inconspicuous among booths pulsing with neon. He played against an opponent who moved with patient geometry; the match stretched and contracted like breath. Marcos felt the same calm focus the software had been cultivating in him, and for the first time in a long time he was not playing to defeat others, but to become more exact, more honest with himself. He won, not because the mouse made him infallible, but because its quiet nudges had aligned something inside his hands and attention.
