defmodule Nombaone.Coupon do
  @moduledoc """
  A reusable discount rule. Applying a coupon to a customer or subscription
  creates a `Nombaone.Discount` — the coupon is the rule, the discount is one
  application of it.

  Exactly one of `amount_off_in_kobo` (integer kobo) or `percent_off` (1–100)
  is non-`nil`. `duration` is one of `once`, `repeating`, `forever`.
