/**
 * QuranRiwaya class provides a clean API for Quran metadata operations
 * with a specific riwaya (recitation tradition) context.
 *
 * Currently provides basic Surah and Ayah operations. For advanced features
 * like Juz, Page, Manzil, RubAlHizb, etc., use the functional API directly.
 *
 * @example
 * **Basic Usage with Hafs**
 * ```typescript
 * import { quran } from 'quran-meta/hafs'
 *
 * const surahMeta = quran.getSurahMeta(2)  // Get Al-Baqarah metadata
 * const ayahCount = quran.getAyahCountInSurah(2)  // 286 ayahs
 * const [surah, ayah] = quran.findSurahAyahByAyahId(100)  // [2, 93]
 * ```
 *
 * @example
 * **Working with Qalun**
 * ```typescript
 * import { quran } from 'quran-meta/qalun'
 *
 * const meta = quran.meta
 * console.log(meta.numAyahs)  // 6214 (Qalun has fewer ayahs than Hafs)
 * ```
 *
 * @example
 * **Creating a custom instance**
 * ```typescript
 * import { QuranRiwaya } from 'quran-meta'
 * import { WarshMeta, WarshLists } from 'quran-meta/lists/WarshLists'
 *
 * const warsh = QuranRiwaya.create(WarshLists)
 * ```
