// Basque Base Phonetic Rules
// ==========================
// Phonetic rules for Basque (Euskara).
// Basque is a language isolate with unique phonology.
//
// Key features:
//   - Simple Latin orthography
//   - Digraphs: tx, ts, tz, tt, dd, rr
//   - X = "sh" sound
//   - Z = "s" sound (NOT like English "z"!)
//   - No F, V in native words
//   - Palatalized consonants: tt, dd
//
// Rule IDs: 4950-4999
