Interface NumericStrategy

The boundary for all arithmetic in Kapom Report. Never write a + b directly in aggregate/computed/runningTotal — it must go through this strategy. The MVP uses nativeNumeric; migrating to decimal.js later won't need to touch the calling logic.

interface NumericStrategy {
    add(a: Decimalish, b: Decimalish): Decimalish;
    divide(a: Decimalish, b: Decimalish): Decimalish;
    multiply(a: Decimalish, b: Decimalish): Decimalish;
    subtract(a: Decimalish, b: Decimalish): Decimalish;
    sum(values: readonly Decimalish[]): Decimalish;
    toNumber(value: Decimalish): number;
}
