.How Roman Numerals works
.- Each round mixes both directions: number to Roman and Roman to number.
- The game calls out subtractive forms so IV, IX, XL, XC, CD, and CM become familiar.
- Build a streak for bonus feedback; pass a level to unlock the next contract.
- The final boss mixes clean numbers, dates, traps, and long inscriptions.
