Implementation Constants

export const NOUN_TYPE_COUNT = 42  // Stage 3: 42 noun types (indices 0-41)
export const VERB_TYPE_COUNT = 127 // Stage 3: 127 verb types (indices 0-126)
export const TOTAL_TYPE_COUNT = 169 // 42 + 127 = 169 types

// Memory footprint for type tracking (fixed-size Uint32Arrays)
// 42 nouns × 4 bytes = 168 bytes
// 127 verbs × 4 bytes = 508 bytes
// Total: 676 bytes (vs ~85KB with Maps) = 99.2% memory reduction
