Field notes
Balances are entered with denomination-specific controls: up to five 500-yen coins, twenty 100-yen coins, and capped counts for the remaining denominations. The payment flow takes a bill amount, proposes how to pay, then lets the user update the remaining balance; the shopping panel asks users to scan or enter tax-inclusive prices and warns that the register total may differ.
