 * Key features:
 * - Inverted tens-ones order: "einundzwanzig" (one-and-twenty) for 21-99
 * - Compound words without spaces below million level
 * - Three forms of 1: "eins" (standalone), "ein" (before hundert/tausend), "eine" (before Million+)
 * - Scale pluralization: Million → Millionen, Milliarde → Milliarden
 * - Spaces only around million+ scale words
 * - BigInt modulo for efficient segment extraction
