At the heart of Orseu lies a pedagogy of movement. It does not teach facts so much as trajectories: how to tilt a problem until a forgotten plane reveals itself; how to unbind assumptions and watch their shadows re-form; how to notice that two apparently unrelated details are quietly entangled.

Each task trains attention like a muscle: steady, repeated, delighted by nuance.
