// Catalan Base Phonetic Rules
// ===========================
// Phonetic rules for Catalan (català).
// Romance language spoken in Catalonia, Valencia, and Balearic Islands.
//
// Key features:
//   - L·L (ela geminada): Geminated l, unique to Catalan
//   - NY: Palatal nasal (like Spanish ñ)
//   - TX: Like English "ch"
//   - TG/TJ: Like English "j"
//   - Ç: s sound
//   - Accents distinguish vowel quality and stress
//   - Eight vowel phonemes: /a/, /e/, /ɛ/, /i/, /o/, /ɔ/, /u/, /ə/
//
// Rule IDs: 4900-4949
