Gematria, Notarikon, Temurahגימטריה

The three letter-arts: gematria (words weighed by number — equal weight, kindred essence), notarikon (words unfolded as acronyms — every word a compressed sentence), temurah (letters exchanged by cipher — atbash swaps first-for-last, and Jeremiah already uses it in scripture: Sheshakh for Babel). Reading as excavation: the text's surface is one of its layers. The letter playground computes all of it live — ⌗ gematria weighs, and ⇄ temurah works all five exchange-wheels (atbash, albam, atbah, avgad, aik bekar).
