`PATCH /api/customers/:customerPublicId`

This uses the same endpoint as [Update Customer](./update-customer). You usually send `packageId`.
Legacy `packageType` values are still accepted for backward compatibility, but they must resolve to a package the organization actually has: a package key or a package display name. An unknown value is rejected with `400` and `data.code` `invalidPackageType`.
