Custom Cloud Functions
Anything at module scope in a function file is shared between tenants. Keep per-tenant state inside the function handler. Call initializeStoker inside the handler too, never at module scope.
Module scope is still the right place for tenant-agnostic setup such as defineSecret or a shared third-party SDK client.
