What happens to a name after it peaks
The Estephania test
Every popular name lives one long story — a climb, a peak, a slow settling back. Zo's later chapters haven't been written yet, so we borrowed them: Estephania climbed just as high around 1992, and its whole arc is on record. Line the two peaks up, and Estephania's path sketches the road Zo is walking now.
Zo sits in the calm middle of the cycle — neither chasing a wave nor sliding off one. Middle-of-the-cycle names age slowly and predictably.
