/**
 * static factories for invoice bodies shared by `sendInvoice` and `createInvoiceLink`.
 *
 * the two variants encode telegram's payment split as types rather than runtime errors:
 * `Invoice.stars` pins `currency` to `"XTR"`, sends an empty `provider_token`, and rejects the fiat-only
 * knobs (tips, shipping, `is_flexible`) while allowing `subscriptionPeriod`; `Invoice.fiat` requires a
 * `providerToken` + ISO 4217 `currency`, allows tips/shipping/flexible, and rejects `subscriptionPeriod`.
 *
 * the result carries every invoice-definition field but no delivery field — spread it into `sendInvoice`
 * (with `chat_id`) or pass it straight to `createInvoiceLink`. add `business_connection_id` at the call site.
 *
 * @example
 * ```ts
 * tg.api.sendInvoice({
 *   chat_id,
 *   ...Invoice.fiat({
 *     title: 'Coffee', description: 'a good cup', payload: 'order_42',
 *     providerToken: process.env.PROVIDER_TOKEN!,
 *     currency: 'EUR',
 *     prices: [LabeledPrice.of('cup', 500), LabeledPrice.of('shipping', 150)],
 *     isFlexible: true
 *   })
 * })
 *
 * const link = await tg.api.createInvoiceLink(Invoice.stars({
 *   title: 'Pro plan', description: 'monthly', payload: 'sub_pro',
 *   prices: [LabeledPrice.of('1 month', 250)],
 *   subscriptionPeriod: 2592000
 * }))
 * ```
