// Thai Base Phonetic Rules
// ========================
// Phonetic rules for Thai (ภาษาไทย) script romanization.
// Maps Thai letters to Latin equivalents for phonetic matching.
//
// Thai is a Brahmic-derived abugida with unique features:
//   - No spaces between words
//   - 5 tones (not fully marked in writing)
//   - 44 consonants in 3 classes (high, mid, low)
//   - Vowels can appear before, after, above, below, or around consonants
//   - Inherent vowel /o/ or /a/ depending on context
//
// Rule IDs: 4500-4599
