/**
 * Hebrew Temurah (Letter Substitution Ciphers)
 *
 * Two ciphers derived from primary historical sources:
 * - Atbash: Jewish Encyclopedia (1903) + Pardes Rimonim (1548)
 * - Albam: Pardes Rimonim (1548), Gate 30, Chapter 5
 *
 * Note: Temurah transforms letters into other letters, not numbers.
 * To get a numeric value, apply gematria to the transformed text.
 *
 * @example
 * ```typescript
 * import { hebrew } from '@metaxia/scriptures-core';
 *
 * // Apply Atbash cipher
 * hebrew.temurah.atbash('בבל')  // 'ששכ' (Babel -> Sheshakh)
 *
 * // Apply Albam cipher
 * hebrew.temurah.albam('אלהים')  // 'למהיב'
 *
 * // Combine with gematria
 * const transformed = hebrew.temurah.atbash('בבל');
 * const value = hebrew.gematria.misparHechrachi(transformed);
 * ```
