Function prorateDiscount

Deprecated

@suluk/stripe is DEPRECATED and gutted (C048) — it is now a thin re-export shell over @suluk/payments and will be REMOVED in the next major. Import everything below from @suluk/payments instead.

What moved to @suluk/payments (re-exported here for backward compatibility): the pricing primitives, the Stripe webhook surface (signature verification + the event router), and the Stripe form-encoder/transport. What was DELETED (dead — no consumer): the Stripe usage-billing (Billing Meters), the checkout-param builders, the shipping/tax adapters, the PaymentProvider/StripeLike types, and restStripe/retrievePaymentIntent. Use @suluk/payments' PaymentConnector (agnostic) or stripeConnector for payment flows.

prorateDiscount(lines: CartLine[], discountCents: number): number[]
Split discountCents across lines proportionally to each line's total, as whole cents that sum EXACTLY to discountCents (largest-remainder apportionment). This is what keeps the cart drawer and the order summary from disagreeing by a cent. Each line's share is clamped to its own total.
Parameters
- lines: CartLine[]
- discountCents: number
Returns number[]
- Defined in pricing.ts:89
