Creem product IDs differ between test and production, which makes billing catalogs harder to manage across environments.
It would be helpful if products had a developer-owned slug/key, for example pro, basic-team, or premium-individual.
This slug should be a stable part of the product identity, so apps can reference products predictably instead of relying only on environment-specific IDs.
This would reduce environment-specific mapping and make pricing, checkout, and entitlement logic easier to keep reliable.
