|----------|-----------------|--------|
| USD | 156.1 × 66.3 × 0.109 | Bureau of Engraving and Printing |

### Exchange Rates
- **Source**: Frankfurter API (https://www.frankfurter.app/)
- **Ultimate Source**: European Central Bank reference rates
- **Update Frequency**: Rates refresh every 30 seconds during active sessions
- **Accuracy Note**: Rates are indicative only, not for financial transactions

Bill organization follows standard banking conventions:
- **Strap**: 100 bills banded together
- **Brick**: 10 straps = 1,000 bills
- **Bundle**: 10 bricks = 10,000 bills

### Calculation Method
1. User enters amount and selects currencies
2. Real-time exchange rate fetched from Frankfurter API
3. Amount converted to target currency
4. Denomination breakdown calculated (highest bills first)
5. 3D scene generated with accurate bill dimensions
6. Human figure (180cm) placed for scale reference
