- **Every fee named and itemized.** Never a lump "Fees".
- The rate line carries its timestamp.
- Uses `Rule` — the same grammar as the statements, which is what makes the library feel like one system.
- Percentage-of-total splits use largest-remainder allocation, so the parts sum to the total exactly.

## Rules this component obeys

Money is minor units, never floats. `null` is not `0` and neither is redacted. Negatives render in accounting parentheses with the parenthesis column reserved on both sides. Debit and credit are two columns. Per-currency decimal places. Polarity is explicit — up is not always good. Every figure states its period, entity, currency, basis and as-of.
